makefiles/consts.mk
makefiles/virtualenv.mk
-----------------------
  o Copy in latest library makefiles from repo:onf-make

global-jjb
packer/common-packer
--------------------
  o Upgrade LinuxFoundation submodules to the latest version.
  o global-jjb           : from=0.53.3 to=0.86.7
  o packaer/common-packer: from=0.1.0~22 to=0.12.1

.gitignore
makefiles/include.mk
makefiles/git/
makefiles/jjb/
--------------
  o Added convenience make targets to view submodule versions.
  o JJB target:jjb-gen added to prototype local pipeline edits.
  o Logic is conditional, library will only load when targets are requested.

jjb/voltha-test/voltha-certification/
jjb/voltha-test/voltha-certification/README
jjb/voltha-test/voltha-certification/master.yaml
------------------------------------------------
  o Create pseudo-branches within voltha testing so we can
  o 'branch' (simple directory copy) at release time VS
  o having to find and clone individual test suites from last release.
