Support existing test types with ASTF

Manual cherry-pick from master [1],
reverting impact of [2] and [3].

[1] https://gerrit.fd.io/r/c/csit/+/28208/176
[2] https://gerrit.fd.io/r/c/csit/+/29077
[3] https://gerrit.fd.io/r/c/csit/+/29529

The heap multipliers are left in suites,
as that simplifies cherry-picking between branches.

Original [0] commit message:
Support existing test types with ASTF
+ Add UDP_CPS, TCP_CPS, UDP_PPS and TCP_PPS suites.
 + Update existing cps traffic profiles.
 + Add missing traffic profiles.
 + UDP:
  + Single burst of 32 packets was confirmed as safe enough for TRex.
  + Maybe 64 could work, but not enough testing for that.
  + Multiple bursts have lead to reduced TRex performance,
    as overlaping bursts (from different client instances)
    tend to fill up the buffers.
 + TCP:
  + Data size set to 11111 bytes, completely arbitrarily.
  + Results look reasonable, so I have kept that.
  - MSS not set at all
 - No tested support for frame size other than 64B.
  - Frame size does not even factor into TCP profiles.
 + So other frame sizes are skipped in autogen.
+ Update tags in related suites.
 - HOSTS_{n} and SRC_USER_{n} should be unified.
 - Questionable clarification on difference between IP4BASE and SCALE.
+ Add NAT state resetters to tests that need them.
 + Resetter is called (if set) before each measurement.
 + If ramp-up is detected, resetter is not set.
+ Rename "mult" argument to "multiplier".
+ Abstracted from packets to transactions.
 + Transaction corresponds to profile.
 + TRex multiplier argument sets target rate in transactions per second.
 + The familiar STL traffic:
  + Bidirectional is considered to be 2 packets per transaction.
  + Unidirectional is considered to be 1 packet per transaction.
 + The newer ASTF traffic:
  + 4 subtypes, each has different number of packets per transaction.
 + For max rate computation:
  + Packets in the more numerous direction are considered.
+ Rely on TRex reported traffic duration for ASTF:
 + Use the server side value.
  - Client side value is higher by an overhead.
  - TRex is not sending traffic during that time.
 + Remove delays from traffic profiles.
  - Those delays would increase the reprted traffic time.
+ Support for scale lmited trials.
 + Only for ASTF profiles, each ASTF profile has limited scale.
 + Scale defined in suite variables.
 + For TRex to send all transactions provided duration value is ignored.
  + The appropriate value is computed in TrafficGenerator.
  + An ad-hoc time constant is added to match the TRex client side time overhead.
  + The profile driver receives the computed duration.
  + Measurement for PLRsearch add a sleep if the computed duration is smaller.
 + Alternative argument for search algos if scale is limited.
  + Both need higher timeout to accomodate big scales.
  + MLRsearch can afford fewer phases.
 + Added a parameter to optionally shorten the duration.
  + Use short duration for runtime stats trial and failure stats trial.
+ Use very large keepalive values in udp profiles to avoid ka packets.
+ No polling in ASTF profile driver.
 - Polling could eliminate the time overhead value.
 + But polling proved to introduce some loss, affecting the results.
+ Handle duration stretching in ASTF by stopping traffic.
 + The stop has several steps so that:
  + The traffic is really stopped entirely.
  + Late packets do not count (maybe as errors).
  + Stats are preserved to read for results (and cleared afterwards).
 + Several quantities added to ReceiveRateMeasurement:
  + Original target duration is preserved (algos need that).
  + Input estimate (tps) for early search iterations.
  + Output estimate (maybe pps) for MRR output.
  + Strict result (unsent counts as loss) for NDR.
+ Use L2 counters (opackets, ipackets) where possible.
 - TRex has trouble processing packets for the L7 ones at high loads.
+ Remove warmup from profile drivers and keywords.
 + Suites should call "Send ramp-up traffic" explicitly if needed.
+ Added parsing for few more counters.
 + Both to use in formulas or just for debug purposes.
- Only 64B cases in autogen, framesize support to be added later.
+ Latency streams during search can be enabled via PERF_USE_LATENCY env var.
+ MLRsearch improvments:
 + Rename argument names to min_rate and max_rate.
 + Use relative receive rate in initial phase.
+ PLRsearch improvements:
 + Careful computation when output (pps) does not match input (tps).
 + Use geometric distribution (instead of Poisson).
  + Helps agains math errors.
  + This should improve estimate stability.
  - But in practice big losses still lead to significant jumps.
+ Traffic generator improvements:
 + send_traffic_on_tg now calls the full set_rate_provider_defaults.
 + _send_traffic_on_tg_internal for the logic without provider defaults.
  + As the internal function is re-used by measure() without affecting defaults.
 + Move _parse_traffic_results just before get_measurement_result.
  + As the latter uses fields set bu the former, it is now easier to read.
 + Multiple sources for approximate duration.
  + Tried from more precise to more available.
 + Includes logic for _pps tests (added in later change).
 + Move explicit type conversions to earlier occurences.
+ Profile driver output field uses semicolons to simplify parsing.
+ Performance Robot lib file split to several smaller ones.
 + performance_actions.robot:
  + Hosts Additional Statistics Action For * keywords.
 + performance_display.robot:
  + Hosts keyword for displaying and verifying results.
  + Change test message to use the correct unit (pps or cps).
 + performance_limits.robot renamed to performance_vars.robot
  + Added many keywords, mostly for accessing test variables.
   + Moved variables for Policer into a new keyword there.
  + Some keywords need sophisticated logic.
  - Other are basically Get Variable Value.
   + But in future more logic can be added, without editing callers.
  + Documentation for the new keywords acts as a documentation for test variables.
 + performance_utils.robot has the rest.
  + Eliminated arguments if the value is in test variable.
  + Small improvements to documentation.
  - Still not enough cleanup with respect to arguments and test variables.
 + Keywords are sorted alphabetically now in each one.
+ Suites:
 + Unified variables table:
  + No colons in comments.
  + ${n_hosts}, ${n_ports} and use them instead hardcoded numbers.
 + Add -cps to existing cps suite names.
  + Remove "trial data overwrite".
  + Compute max rate as in STL suites.
 + Each NAT suite has ip4base suite to compare results to.
  - Those act as indirect TRex calibration.
  - VPP does not lose packets in those.
 + Latency in ASTF suites is disabled hard.
  - As we do not support latency in ASTF profiles yet.
 + Unidirectional tests governed by suite variable, not an argument.
+ Write long argument lists vertically.
 + Prefer to use argument names.
 + In Python, also the last argument is followed by comma.
 + It makes renaming and reordering easier.
 + Similarly applies to prints with long lists of values.
+ A TODO to update api crc file comments.

+        This method contains the logic to compute duration as maximum time
+        if transaction_scale is nonzero.
+        The transaction_scale argument defines (limits) how many transactions
+        will be started in total. As that amount of transaction can take
+        considerable time (sometimes due to explicit delays in the profile),
+        the real time a trial needs to finish is computed here. For now,
+        in that case the duration argument is ignored, assuming it comes
+        from ASTF-unaware search algorithm. The overall time a single
+        transaction needs is given in parameter transaction_duration,
+        it includes both explicit delays and implicit time it takes
+        to transfer data (or whatever the transaction does).
+
+        Currently it is observed TRex does not start the ASTF traffic
+        immediately, an ad-hoc constant is added to the computed duration
+        to compensate for that.
+
+        If transaction_scale is zero, duration is not recomputed.
+        It is assumed the subsequent result parsing gets the real duration
+        if the traffic stops sooner for any reason.
+
+        Currently, it is assumed traffic profile defines a single transaction.
+        To avoid heavy logic here, the input rate is expected to be in
+        transactions per second, as that directly translates to TRex multiplier,
+        (assuming the profile does not override the default cps value of one).

+| Get Transaction Scale
+| | [Documentation]
+| | ... | Return value of \${transaction_scale} variable,
+| | ... | or \${0} if not defined.
+| |
+| | ... | Zero return value means the number of transactions is not limited,
+| | ... | which is true for most STL TRex profiles (transaction is a packet).
+| | ... | Nonzero return value means the number of transactions is fixed,
+| | ... | for example in stateful NAT scale tests.

+| | ... | Return value of \${transaction_type} variable,
+| | ... | or "packet" if not defined.
+| |
+| | ... | The return value describes the type of transaction
+| | ... | the test is executed. For example "packet" means a transaction
+| | ... | is just a single packet. For more sophisticated transactions,
+| | ... | the logic to determine the number of passed transactions
+| | ... | is different from merely counting the packets received from DUT.
+| | ... | Return type: string.
+| |
+| | ... | *Example:*
+| |
+| | ... | \| \${transaction_type} = \| Get Transaction Type \|
+| |

+| Set Jumbo
+| | [Documentation]
+| | ... | For jumbo frames detection, the maximal packet size is relevant,
+| | ... | encapsulation overhead (if any) has effect.
+| |
+| | ... | This keyword computes jumbo boolean (some suites need that for

+| | ... | For jumbo frames detection, the maximal packet size is relevant.
+| | ... | For maximal transmit rate, the average packet size is relevant.
+| | ... | In both cases, encapsulation overhead (if any) has effect.
+| | ... | The maximal rate is computed from NIC name.

+| | ... | Framesize can be either integer in case of a single packet
+| | ... | in stream, or set of packets in case of IMIX type or simmilar.
+| | ... | For jumbo decisions, we need a numeric size of the biggest packet.

+| | ... | This keyword computes both and sets them as test variables.
+| |
+| | ... | Each suite sets a value named \${overhead},

+| | ... | can be negaive (if TG-DUT is encapsulated more heavily).
