After oslo.messaging port is done, we'll need to initialize RPC layer from all RPC agents. We'll put initialization into init() function, so the first step for migration is to make agents use it. The function is renamed to be explicit about the fact that we don't just parse configuration by calling it, but also do other common initializations, like setting RPC layer. blueprint oslo-messaging Change-Id: I71c62f270ac7a1ff1426a3f49a32133b65580e35
