A partial upgrading of neutron cluster, neutron-server
has a newer version while neutron-agents not, does not
run well after a RPC data structure upgrading. This
patch upgrades the security group related RPC version
between neutron-server and agents. A partial upgrading
neutron cluster will explicitly raise error. The RPC
version should be aligned.
