Each service implemented the get_backdoor_port method individually. This patch moves the implementation of this method to the base rpc API instead, and removes the now unnecessary code from each of the services. The server side method was left on all of the managers for rpc backwards copmatibility. They can be removed on the next major rpc version bump of those APIs. Part of blueprint base-rpc-api.
