    Ensure rsyncd PID file is removed during overcloud updates

    During an overcloud update it might happen that the rsyncd container
    gets killed & restarted, leaving a PID file from rsyncd. rsyncd won't
    start because of this, which results in a container restarting loop.

    This patch ensures the PID file is absent to fix this.
