Russell Bryant f76110be99 Convert several uses of RpcCallback
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.
