Subject: [PATCH] Add client_id_metadata_document_supported to OAuthMetadata

Add support for the client_id_metadata_document_supported field as
specified in draft-parecki-oauth-client-id-metadata-document-00. This
boolean field indicates whether the authorization server supports
retrieving client metadata from a client_id URL.
