Update all of the rpc client API classes to include a version alias for the latest version implemented in Juno. This alias is needed when doing rolling upgrades from Juno to Kilo. With this in place, you can ensure all services only send messages that both Juno and Kilo will understand. Change-Id: Ia81538130bf8530b70b5f55c7a3d565903ff54b4
