now，machines in openstack cloud find other node by query conrol-node should Nova or Quantum contain a protocol to Find a new Node ,and no need for controler-Node,just become a operating system like ubuntu,

1 Find、identify、Authorize、use compute service

2 Find、identify、Authorize、use stock service

Every node machine should be the same（openstack deployed module） except id，and no “control-node”，just all for one，one for all

Every node machine should have a “ID” just like “IP”
