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.
