[VOL-5315] Add support for tool pre-commit and repo:onf-make
.pre-commit-config.yaml
-----------------------
o Install basic config for pre-commit tool use.
lf/transition.mk
----------------
o Legacy mode: add deps to checkout submodule
when repo:onf-make library makefiles are included.
lf/onf-make/makefiles/commands/pre-commit/
------------------------------------------
o Define convenience target 'pre-commit
o A virtualenv is installed on demand as a dependency.
o Invoke tool pre-commit.
lf/
Makefile
.gitmodules
-----------
o Add repo:onf-make as a git submodule.
o Facilitate replacing local copy & paste makefiles/ with
a refactored library equivalent.
