mod_cloud_notify: Identify (and immediately push) urgent stanzas, e.g. calls
This covers the following things:
- A session that appears online, but has a broken TCP connection
- Clients such as Siskin and Snikket iOS that require a push for calls to work
It allows the stanza to be pushed immediately instead of waiting for the
session to hibernate or an ack to timeout.
It shouldn't break any existing cases.
