Update rpc version aliases for juno

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.
