Fix a repository issue

jjb/software-upgrades.yaml
--------------------------
  o Added a copyright notice.
  o Cosmetic yaml edits to force a job to run.

jjb/pipeline/voltha/software-upgrades.groovy
--------------------------------------------
  o Changed https://github to https://gerrit for consistency.
  o Branch deletions are not mirrored out to github and stray
    entries can cause problems for docker image retrieval.
  o Querying gerrit (current source of truth) will return valid branches.

test/bats/
----------
  o Add BATS unit tests to validate 'git ls' code snippet
    from the software-upgrade.groovy pipeline script.
