mod_pubsub_serverinfo: New module that uses pub/sub to make accessible server info
This first implemetnation is laughably simple: it only adds a disco#info
feature. This flags 'opt-in' for inclusion of local domain names in the
data exposed by other domains (per the domain), which will allow servers to
be listed in the XMPP Network Graph at https://xmppnetwork.goodbytes.im
Hopefully, this bare-boned implementation acts as a stepping stone for
future improvements.
