[Tarantool-patches] [PATCH v2] Add exclude option as suite/test pattern

[Alexander V. Tikhonov]

Added exclude option to be able to exclude the tests
by patterns suite/test from testing, it means that
exclude option even excludes the suites given with
option suite either test pattern.
Also added ability to set the list of exclude patterns
by the environment variable TEST_RUN_EXCLUDE_TESTS.

Close #54
