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.
