mod_http_oauth2: Improve error messages for URI properties
Since there are separate validation checks for URI properties, including
that they should use https, with better and more specific error reporting.
Reverts 'luaPattern' to 'pattern' which is not currently supported by
util.jsonschema, but allows anything that retrieves the schema over http
to validate against it, should they wish to do so.

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 ``` | |
