A unit test for validating repository tags.

lf/include.mk
-------------
  o Handle a bootstrap case for git submodule checkout.
  o Invoke git command using macro $(GIT) else not found by path.
  o git submodule update --init --recursive will checkout repo:onf-make

test/bats/check_repo_tags.bats
------------------------------
  o A BATS unit test to validate contents of gerrit and github repository tags.
  o Replace inlined hardcoded list of repository names.
  o Instead read them from data file conf/repos/voltha.
  o Added conditional booleans enable_fatal= and enable_skip=1
    for easy removal of test filtering while using interactively.

test/bats/conf/repos/deprecated
-------------------------------
  o Move a few repositories into a new deprecated list so their usage is clear.
