Makefile library merge with onf-make and voltha-lib-go
makefiles/
----------
o Import standalone makefile directories to checkin smaller parts of a mega patch.
o Build out directory hierarchy by topic and feature.
makefiles/lint/yaml/
--------------------
o Pull in logic evolved in repo:voltha-lib-go.
o Refactoring: support special snowflake targets by repository.
o ci-management and voltha-lib-go use distinct yamllint.conf files.
o Separate until there is time to review and consolidate.
o Added deps for on-demand local install of yamllint.
- requirements.txt could be used but every build would incur overhead.
Makefile
--------
o Use latest syntax from repo:onf-make.
o No need to set path variables, makefiles/include.mk can infer them.
o Added a help target to explicitly display targets and suggestions.
o Logic is bundled in libraries and use of 'make help' is not well known.
