Serveral IPSec SPD cases re-use the same test class name,
leads to test error when do parrallel test with TEST_JOBS=16,
change the test class names to unique values.

Drop pycodestyle for code style checking in favor of black. Black is
much faster, stable PEP8 compliant code style checker offering also
automatic formatting. It aims to be very stable and produce smallest
diffs. It's used by many small and big projects.
Running checkstyle with black takes a few seconds with a terse output.
Thus, test-checkstyle-diff is no longer necessary.
Expand scope of checkstyle to all python files in the repo, replacing
test-checkstyle with checkstyle-python.
Also, fixstyle-python is now available for automatic style formatting.
Note: python virtualenv has been consolidated in test/Makefile,
test/requirements*.txt which will eventually be moved to a central
location. This is required to simply the automated generation of
docker executor images in the CI.

Adding flow cache support to improve inbound IPv4/IPSec Security Policy
Database (SPD) lookup performance. By enabling the flow cache in startup
conf, this replaces a linear O(N) SPD search, with an O(1) hash table
search.
This patch is the ipsec4_input_node counterpart to
https://gerrit.fd.io/r/c/vpp/+/31694, and shares much of the same code,
theory and mechanism of action.
Details about the flow cache:
Mechanism:
1. First packet of a flow will undergo linear search in SPD
table. Once a policy match is found, a new entry will be added
into the flow cache. From 2nd packet onwards, the policy lookup
will happen in flow cache.
2. The flow cache is implemented using a hash table without collision
handling. This will avoid the logic to age out or recycle the old
flows in flow cache. Whenever a collision occurs, the old entry
will be overwritten by the new entry. Worst case is when all the
256 packets in a batch result in collision, falling back to linear
search. Average and best case will be O(1).
3. The size of flow cache is fixed and decided based on the number
of flows to be supported. The default is set to 1 million flows,
but is configurable by a startup.conf option.
4. Whenever a SPD rule is added/deleted by the control plane, all
current flow cache entries will be invalidated. As the SPD API is
not mp-safe, the data plane will wait for the control plane
operation to complete.
Cache invalidation is via an epoch counter that is incremented on
policy add/del and stored with each entry in the flow cache. If the
epoch counter in the flow cache does not match the current count,
the entry is considered stale, and we fall back to linear search.
The following configurable options are available through startup
conf under the ipsec{} entry:
1. ipv4-inbound-spd-flow-cache on/off - enable SPD flow cache
(default off)
2. ipv4-inbound-spd-hash-buckets %d - set number of hash buckets
(default 4,194,304: ~1 million flows with 25% load factor)
Performance with 1 core, 1 ESP Tunnel, null-decrypt then bypass,
94B (null encrypted packet) for different SPD policy matching indices:
SPD Policy index : 2 10 100 1000
Throughput : Mbps/Mbps Mbps/Mbps Mbps/Mbps Mbps/Mbps
(Baseline/Optimized)
ARM TX2 : 300/290 230/290 70/290 8.5/290
