mod_http_oauth2: Apply refresh token ttl to refresh token instead of grant
The intent in 59d5fc50f602 was for refresh tokens to extend the lifetime
of the grant, but the refresh token ttl was applied to the grant and
mod_tokenauth does not change it, leading to the grant expiring
regardless of refresh token usage.
This makes grant lifetimes unlimited, which seems to be standard
practice in the wild.

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 | |
