  - Merge "Functest: Sets max concurrent jobs to 10"
  - Functest: Sets max concurrent jobs to 10

    In Apex, some random jobs are queueing to intel-pod11 which does not
    exist anymore. The problem is, when these jobs queue they are blocking
    apex daily functest, as it looks like the job is only set to allow 1 job
    globally at a time. This change bumps the max concurrent global jobs to
    10.
