makefiles/
----------
o Adding more lint target logic.
o Copy in virtualenv.mk from voltha-docs to support dependency
based virtualenv installations.
*/*.yaml
--------
o Misc yamllint cleanups.
Makefile
--------
o Prune inlined logic since replaced by library makefile logic.
o Replaced explicit pyenv installation with dependency driven
so venv will only require installation once per target run.
o Library make clean/sterile targets handle cleanup.
