    METRON-1078: Metron Indexing fails to stop during "Stop All Services"

    ## Contributor Comments
    There is a corner-case where sometimes the Storm REST UI is stopped before the Metron
topologies when 'STOP ALL' is selected from Ambari. This PR orders STORM_REST_API-STOP after
the Metron topologies STOP.
    To verify, spin up full-dev and select 'Stop All' from the UI. Verify that 'Storm UI Server
Stop' comes after all the the Metron topologies.
