tests: make tests less make dependent
Implement command line argument parsing instead of passing arguments via environment variables. Add script for running tests without having to invoke make. Deprecate running tests via make.

- Arguments controlling test runs:
- V=[0|1|2] - set test verbosity level
- 0=ERROR, 1=INFO, 2=DEBUG
- TEST_JOBS=[<n>|auto] - use at most <n> parallel python processes for test execution, if auto, set to number of available cpus (default: 1)
- MAX_VPP_CPUS=[<n>|auto]- use at most <n> cpus for running vpp main and worker threads, if auto, set to number of available cpus (default: auto)
- CACHE_OUTPUT=[0|1] - cache VPP stdout/stderr and log as one block after test finishes (default: 1)
- FAILFAST=[0|1] - fail fast if 1, complete all tests if 0
- TIMEOUT=<timeout> - fail test suite if any single test takes longer than <timeout> (in seconds) to finish (default: 600)
- RETRIES=<n> - retry failed tests <n> times
- DEBUG=<type> - set VPP debugging kind
- DEBUG=core - detect coredump and load it in gdb on crash
- DEBUG=gdb - allow easy debugging by printing VPP PID
- and waiting for user input before running
- and tearing down a testcase
- DEBUG=gdbserver - run gdb inside a gdb server, otherwise
- same as above
- DEBUG=attach - attach test case to already running vpp in gdb (see test-start-vpp-in-gdb)
-
- STEP=[yes|no] - ease debugging by stepping through a testcase
- SANITY=[yes|no] - perform sanity import of vpp-api/sanity vpp run before running tests (default: yes)
- EXTENDED_TESTS=[1|y] - used by '[re]test-all' & '[re]test-all-debug' to run extended tests
- TEST=<filter> - filter the set of tests:
- by file-name - only run tests from specified file, e.g. TEST=test_bfd selects all tests from test_bfd.py
- by file-suffix - same as file-name, but 'test_' is omitted e.g. TEST=bfd selects all tests from test_bfd.py
- by wildcard - wildcard filter is <file>.<class>.<test function>, each can be replaced by '*'
- e.g. TEST='test_bfd.*.*' is equivalent to above example of filter by file-name
- TEST='bfd.*.*' is equivalent to above example of filter by file-suffix
- TEST='bfd.BFDAPITestCase.*' selects all tests from test_bfd.py which are part of BFDAPITestCase class

-
- VARIANT=<variant> - specify which march node variant to unit test
- e.g. VARIANT=skx test the skx march variants
- e.g. VARIANT=icl test the icl march variants
-
- COREDUMP_SIZE=<size> - pass <size> as unix { coredump-size <size> } argument to vpp
- e.g. COREDUMP_SIZE=4g
- COREDUMP_SIZE=unlimited
- COREDUMP_COMPRESS=1 - compress core files if not debugging them
- EXTERN_TESTS=<path> - path to out-of-tree test_<name>.py files containing test cases
- EXTERN_PLUGINS=<path> - path to out-of-tree plugins to be loaded by vpp under test
- EXTERN_COV_DIR=<path> - path to out-of-tree prefix, where source, object and .gcda files can be found for coverage report
-
- PROFILE=1 - enable profiling of test framework via cProfile module
- PROFILE_SORT_BY=opt - sort profiling report by opt - consult cProfile documentation for possible values (default: cumtime)
- PROFILE_OUTPUT=file - output profiling info to file - use absolute path (default: stdout)
-
- TEST_DEBUG=1 - turn on debugging of the test framework itself (expert)
-
- SKIP_AARCH64=1 - skip tests that are failing on the ARM platorm in FD.io CI
-
- RND_SEED=seed - Seed RND with given seed
-
- Starting VPP in GDB for use with DEBUG=attach:
-
- test-start-vpp-in-gdb - start VPP in gdb (release)
- test-start-vpp-debug-in-gdb - start VPP in gdb (debug)
-
- Arguments controlling VPP in GDB runs:
-
- VPP_IN_GDB_TMP_DIR - specify directory to run VPP IN (default: /tmp/unittest-attach-gdb)
- VPP_IN_GDB_NO_RMDIR=0 - don't remove existing tmp dir but fail instead
- VPP_IN_GDB_CMDLINE=1 - add 'interactive' to VPP arguments to run with command line
