mod_http_oauth2: Skip consent screen if requested by client and same scopes already granted
This follows the intent behind the OpenID Connect 'prompt' parameter
when it does not include the 'consent' keyword, that is the client
wishes to skip the consent screen. If the user has already granted the
exact same scopes to the exact same client in the past, then one can
assume that they may grant it again.
