[CORD-3256] Generate TT/TP community test job.

jjb/voltha-test/voltha.yaml
jjb/voltha-test/voltha-nightly-jobs.yaml
----------------------------------------
  - First attempt at cloning a voltha pipeline job from DT to TT.
  - Add a few placeholders for future work to split yaml configs
    into a more modular setup.

Makefile
config.mk
makefiles/lint/groovy.mk
makefiles/lint/yaml.mk
makefiles/virtualenv.mk
------------------------
  - Copy in makefile libraries from repo::voltha-docs.
  - lint/yaml and lint/groovy.

Misc / Fixes
------------
  - Fixed colorization in tree output.
  - Comment out jjb import in requirements.txt, Makefile still configured to use an older version.
  - Move README.md outside jjb/ lf-env scripts blindly grep for error patterns beneath jjb/
