In order to avoid unecessary server to client pings, the server needs to be aware of the default idle-interval after which a client will ping the server.
TODO/WIP TEXT: Defines a mechanism allowing the client to tell the server that the client will never keep the connection idle longer then a certain period of time. This avoid the patholgical case where pings from send by the server to check if the connection is still alive wakes a sleeping client up.
TODO: Add after the XEP leaves the 'experimental' state.
Thanks to everyone who provided feedback.
