With the change to oslo.context in the depends-on, we no longer need to maintain an override for the from_dict function. We only need to provide a list of additional keys in the appropriate class member. This will work with oslo.context 2.19.2 and above, which is now the minimum version in global-requirements. Depends-On: Ib143f8a5c129dbf6711800c4d87c8830a8aa3365 Change-Id: If09a3b22465b196baa34edc00c7472f5feed4ba5
