When stopping services Cinder doesn't wait for periodic tasks

[Gorka Eguileor]

When a Service in cinder stops we stop the periodic tasks but then we don't wait for them to properly stop.

wait method in Service class should be waiting for the FixedIntervalLoopingCall tasks to stop before exiting.

    Wait for periodic tasks to stop on exit

    When a Service in Cinder exits it stops all operations and waits for
    them to complete, and it also stops all periodica tasks created with
    FixedIntervalLoop, but it doesn't wait until these are completed.

    This patch will wait for all periodic tasks that received the stop
    request without raising an exception before exiting.
