      .New `pcs status wait` command

      The `pcs` command-line interface now provides a `pcs status wait` command. This command ensures that Pacemaker has completed any actions required by changes to the Cluster Information Base (CIB) and does not need to take any further actions in order to make the actual cluster state match the requested cluster state.

      Intended use spurred with bz1619265 is:

      perform bunch of changes to cluster state/configuration, only then arrange for waiting until it all sinks in and the cluster at pacemaker level finally "settles"

      Implementation-wise:

      crm_resource --wait [--timeout=TIMEOUT]

      Notes:

      • modeled according to "udevadm settle" (and perhaps others) administrators can be familiar with
      • why not just "pcs cluster settle"? there are more in-flight, transients states that one may also want to establish "sequential points" for, e.g. "pcs cluster start"; "pcs cluster settle" could then easily be dedicated to mean as a catch-all (or smart decision to be made automatically) later on
