+ Bump T-Rex version. We need new features for ASTF test.
+ Apply core pining. Results in a more stable performance.
+ Tweak the number of T-Rex workers.
+ We need an even value to achieve ymmetric performance with pinning.
+ Value 8 was selected as a best compromise.
This is a combination of 3 commits.
This is the 1st commit message:
T-Rex: 2.82
This is the commit message #2:
Change Trex to CORE_MASK_PIN mode to improve performance
https://trex-tgn.cisco.com/trex/doc/trex_stateless.html#_core_masking_per_interface
Above link have below explaination,
"When the profile is symmetric, performance can be improved by pinning half of
the cores to port 0, and half of the cores to port 1, thus avoiding cache
trashing and bouncing."
The reason to change this is that to run CSIT with 100G NIC often failed with
"TRex stateless runtime error timeout", it caused by Trex can not send enough
traffic within the fixed duration.
by change to CORE_MASK_PIN mode fix the issue.
Not editing ASTF, as that supports different options.
This is the commit message #3:
Experiment: Vary number of TRex workers
With CORE_MASK_PIN, we can get more predictable time distribution.
Decided to use 8 workers, that gives good results
both for high end (RDMA-core l2patch) and low end (vhost) tests.

- continuation of https://gerrit.fd.io/r/c/csit/+/26898 as there was
reached limit of changes (1000)
Jira: CSIT-1711
- udp synthetic profiles w/o data packets
- udp cps perf tests, phase I (no special "search cps" KW)
Part I means that we are using MRR tests to collect traffic data
until there is ready new CPS test type with corresponding algorithm.

+ Keep apache license for now, until this is completed:
https://wiki.fd.io/view/TSC/Relicensing_Procedure
+ Add utilities for switching license comment blocks.
- They do not preserve attributes, so executable flag is lost.
+ Move the affected files to GPL/.
+ Update paths so files are executed from the new location.
+ Change the way scripts are started to do not require executable flag.
+ Employ OptionString when constructing longer command lines.
+ Move also PacketVerifier.py and TrafficScriptArg.py
as they are linked with traffic scripts.
+ That means the two files are outside "resources" package tree now.
+ Added __init__.py files so relative imports work in new package tree.
+ Start traffic scripts as python modules to allow relative imports.
+ Once again needed because they are outside the default PYTHONPATH.
