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).
