tests: refactor asf framework code

- Make framework.py classes a subset of asfframework.py classes
- Remove all packet related code from asfframework.py
- Add test class and test case set up debug output to log
- Repatriate packet tests from asf to test directory
- Remove non-packet related code from framework.py and
  inherit them from asfframework.py classes
- Clean up unused import variables
- Re-enable BFD tests on Ubuntu 22.04 and fix
  intermittent test failures in echo_looped_back
  testcases (where # control packets verified but
  not guaranteed to be received during test)
- Re-enable Wireguard tests on Ubuntu 22.04 and fix
  intermittent test failures in handshake ratelimiting
  testcases and event testcase
- Run Wiregard testcase suites solo
- Improve debug output in log.txt
- Increase VCL/LDP post sleep timeout to allow iperf server
  to finish cleanly.
- Fix pcap history files to be sorted by suite and testcase
  and ensure order/timestamp is correct based on creation
  in the testcase.
- Decode pcap files for each suite and testcase for all
  errors or if configured via comandline option / env var
- Improve vpp corefile detection to allow complete corefile
  generation
- Disable vm vpp interfaces testcases on debian11
- Clean up failed unittest dir when retrying failed testcases
  and unify testname directory and failed linknames into
  framwork functions
