  - Merge "Reduce Basic Job Duplication"
  - Reduce Basic Job Duplication

    In the initial formation of projects we found it easy to copy job
    definitions to provide project a baseline job config to work off. This
    has led to a lot of duplication and misalignment with the gerrit
    triggers and default build server tag to be used.

    Collapsing these jobs into a job-group containing the stream and a
    verify job per-stream, should help reduce this duplication.
