    /*
    Job type can be "service", "batch" or "system".
        A "service" job is made for long lived services that should never go down,
        Service jobs are made to run until explicitly stopped by the operator.
    A "batch" job is made for short lived operations which can last
    from a couple of minutes to a few days.
    Batch schedulers are very similar to Service schedulers but with a few optimizations,
    for the batch workload.
    Batch jobs are intended to run until the job is successful, if the Batch task
    exits with an error it will be handled according to the job's restart 
    and reschedule stanzas.
    A "system" job is made for registering jobs that should be run on every client,
    that has job's constraints.
    The system job is also used when clients join the cluster or transition into the,
    ready state.
