mod_http_oauth2: Allow 'login_hint' as a substitute for OIDC 'select_account' prompt If the OIDC 'prompt' parameter does not contain the 'select_account' then it wants us to skip account selection, which means we have to figure which account to authenticate somehow. One way could be have this stored in a cookie from a previous successful login. Another way would be to have the account passed as a hint, which is what we add here.

Prosody 0.12 added an API allowing modules to report their status. This
module allows reading these statuses via HTTP for use in monitoring.

```
$ curl http://prosody.localhost:5280/status
{
   "example.com" : {
      "c2s" : {
         "message" : "Loaded",
         "type" : "core"
      }
   }
}
```
