rest server: cleanup auth-log handling

Handle auth logs the same way as access log.
- Configure with ApiConfig
- CommandoSocket command to reload auth-logs "api-auth-log-reopen"

Inside API calls, we now access the ApiConfig using the RestEnvironment.

The openid_login api now also logs failed logins and return http_err!(UNAUTHORIZED, ..)
on failed logins.
