Convert several places in the code that were using the RpcCallback compatibility class. This class eased the transition to oslo.messaging. This patch drops the usage of this class in favor of direct usage of the appropriate oslo.messaging API. Part of blueprint drop-rpc-compat. Change-Id: I955958e836635d43dabc7b39d050c1418b18cf8f
