mod_service_outage_status: XEP-0455: Service Outage Status

Only the out of band part so far.

The in-band pubsub part would need '+notify' support in mod_pubsub,
since mod_pep does not serve the bare-host-JID.

All the hard parts of this XEP is elsewhere, i.e. hosting the document
somewhere reliable.

+This module allows advertising a machine-readable document were outages,
+planned or otherwise, may be reported.
+
+See [XEP-0455: Service Outage Status] for further details, including
+the format of the outage status document.
+
+```lua
+modules_enabled = {
+    -- other modules
+    "service_outage_status",
+}
+
+outage_status_urls = {
+    "https://uptime.example.net/status.json",
+}
+```
+
+The outage status document should be hosted on a separate server to
+ensure availability even if the XMPP server is unreachable.
