This allows the OpenID userinfo endpoint to be active even if the federation resource is not active. The OpenID userinfo endpoint is called by integration managers to verify user actions using the client API OpenID access token. Without this verification, the integration manager cannot know that the access token is valid. The OpenID userinfo endpoint will be loaded in the case that either "federation" or "openid" resource is defined. The new "openid" resource is defaulted to active in default configuration.
