Chaoyi Huang 81b45f2c1d Move statless design from experiment to master branch
The statless design was developed in the experiment branch, the experiment
shows advantage in removing the status synchronization, uuid mapping
compared to the stateful design, and also fully reduce the coupling with
OpenStack services like Nova, Cinder. The overhead query latency for
resources also acceptable. It's time to move the statless design to the
master branch
