If a task in a parallel job fails and it was launched with the
    --kill-on-bad-exit option then terminated the remaining tasks using the
    SIGCONT, SIGTERM and SIGKILL signals rather than just sending SIGKILL.

Sinfo command with support for federated clusters

The job was completing before the test could find that the job was
running. The script was running for 10 seconds and wait_for_fed_job can
back off and check only every 10 seconds.

Can't use the revoked state to determine if the job is pending or not
since an origin job could be revoked if it doesn't have an active job on
itself.

If there were no clusters in the system then the dbd would insert a row
in the database and then on the next time the dbd would start (with no
clusters) it would attempt to insert the row again and fatal. Now it
always makes a query against the database and if there are no clusters
in the system, then it inserts the current db version into the table.
