    glusterd: Don't spawn new glusterfsds on node reboot with brick-mux

    With brick multiplexing enabled, upon a node reboot new bricks were
    not being attached to the first spawned brick process even though
    there wasn't any compatibility issues.

    The reason for this is that upon glusterd restart after a node
    reboot, since brick services aren't running, glusterd starts the
    bricks in a "no-wait" mode. So after a brick process is spawned for
    the first brick, there isn't enough time for the corresponding pid
    file to get populated with a value before the compatibilty check is
    made for the next brick.

    This commit solves this by iteratively waiting for the pidfile to be
    populated in the brick compatibility comparison stage before checking
    if the brick process is alive.
