mod_cloud_notify: Cleanup code and drop support for prosody 0.9 This removes some legacy stuff that was needed for prosody 0.9 We now use util.stanza:find instead of our own patched version to be more mainstream The unneeded module unloading code was removed, too

-- this module is deprecated, log an error and load the superseding module instead
