VOL-5160 - Repo triage build for release branching.
Makefile
makefiles
---------
o Copy in library makefiles from repo:onf-make.
o Selectively enable constants and library logic.
o Cleanup and refactoring effort is needed to enable bulk docker and lint
targets but that effort is deferred to a separate jira ticket.
VERSION
-------
o Change *-dev branch to a release version to exercise all pipeline
job steps (including task publish if any).
