mod_ping_muc: Delay ping a configurable amount of time
If a server is restarting, checking immediately before it has a chance
to complete its restart and get ready would often fail, preventing the
possibility of transparent restarts as supported by Prosody's mod_muc.
Reconnecting immediately when a connection is closed for being idle, or
because the remote server is trying to reclaim some resources, is also
counter-productive as the connection may fail.
Also, if there is some Internet routing problem affecting s2s, it may
help to wait a bit before checking, in case the problem resolved itself
in the mean time.
