    glusterd: double-check whether brick is alive for stats

    With multiplexing, our tests detach bricks from their host processes
    without glusterd being involved.  Thus, when we ask glusterd to fetch
    profile info, it will try to fetch from a brick that's actually not
    present any more.  While it can handle the process being dead and its
    RPC connection being closed, it barfs if it gets a negative response
    from a live brick process.  This is not a problem in normal use,
    because the brick can't disappear without glusterd seeing it.  The fix
    is to double check that the brick is actually running, by looking for
    its pidfile which the tests *do* clean up as part of killing a brick.
