    ctdb-tests: Reimplement daemons_stop() using ctdbd_wrapper
    
    The current daemons_stop() implementation uses very loose matching to
    decide which processes to kill if "ctdb shutdown" hasn't worked within
    1 second.  This can cause ctdbd processes from other test runs to be
    killed.
    
    Instead, use ctdbd_wrapper, which uses the PID file as a last resort.
    This has the advantage of never killing ctdbd processes from other
    test runs.  However, this also has the obvious consequence that an
    interrupted test run in one directory can not have its daemons cleaned
    up from a new test run in a different directory.
