mod_http_oauth2: Allow requesting a subset of scopes on token refresh
This enables clients to request access tokens with fewer permissions
than the grant they were given, reducing impact of token leak. Clients
could e.g. request access tokens with some privileges and immediately
revoke them after use, or other strategies.
