mod_http_oauth2: Specify that 'contacts' items are emails in client registration
Not enforced, but good for documentation.
> Array of strings representing ways to contact people responsible for
> this client, typically email addresses.
"typically" isn't a great word in a specification, so one could persume
this may be e.g. URLs like https://example.com/contact-us or so as well.

::: {.alert .alert-warning} This module is an experiment about a more graceful shutdown process. Graceful shutdown has now been implemented in Prosody trunk and will be part 0.12. See [issue #1225](https://issues.prosody.im/1225) for details. ::: Why === When shutting down, a number of sessions, connections and other things are teared down. Due to all these things happening very quickly, sometimes e.g. client unavailable notifications don't make it to all remote contacts because the server-to-server connections are teared down just after. How === This module works by breaking the shutdown process into separate steps with a brief pause between them. It goes something like this 1. Stop accepting new client connections. 2. Close all client connections. 3. Fire event for everything else. 4. Tell `net.server` to quit the main loop. 5. ??? 6. Still here? Kill itself.
