  - Merge "Make multiple integration jobs voting"
  - Make multiple integration jobs voting

    A risk exists that we just sort of ingore an integration job
    failure with an IPA change which might be a legitimate issue.

    The key is that we really need to just fix the jobs when they
    fail, and not leave jobs in non-voting status for long periods
    of times.

    So this, in order to help head off merging breaking changes
    which might break a non-voting job, elevates those non-voting
    jobs to voting.
