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.

16 First, download and add the module to `module_enabled`. Then you can |
| 1842 | 17 decide on what policy you want to have. |
| 18 | |
| 19 Requiring ciphers with forward secrecy is the most simple to set up. | |
| 20 | |
| 21 ``` lua | |
| 22 tls_policy = "FS" -- allow only ciphers that enable forward secrecy | |
| 23 ``` | |
| 24 | |
| 25 A more complicated example: | |
| 26 | |
| 27 ``` lua | |
| 28 tls_policy = { | |
| 29 c2s = { | |
| 30 encryption = "AES"; -- Require AES (or AESGCM) encryption | |
| 31 protocol = "TLSv1.2"; -- and TLSv1.2 | |
| 32 bits = 128; -- and at least 128 bits (FIXME: remember what this meant) | |
| 33 } | |
| 34 s2s = { | |
| 35 cipher = "AESGCM"; -- Require AESGCM ciphers | |
| 36 protocol = "TLSv1.[12]"; -- and TLSv1.1 or 1.2 | |
| 37 authentication = "RSA"; -- with RSA authentication | |
| 38 }; | |
| 39 } | |
| 40 ``` | |
| 41 | |
| 42 # Compatibility | |
| 43 | |
| 44 Requires LuaSec 0.5 | |
