Dongfeng Huang 5cbf4c74e6 Synchronized patch: Nova API-Gateway Server Action Support(part2) 
1. What is the problem
Originally this patch was committed to the Tricircle and provided
server action support, but after Tricircle narrowed its scope to
networking automation across Neutron, these API-Gateway features
implemented in this patch were no longer used. However Trio2o needs
these functions, so we plan to synchronize this patch from Gerrit
to Trio2o. You can find the old patch on Gerrit here[1].

The current Nova API-Gateway does not support following server actions:
   reboot: Reboot a server
   resize: Resize a server
   confirmResize: Confirm a pending resize action for a server
   revertResize: Cancel and revert a pending resize action for a server
   os-resetState: Reset the state of a server

2. What is the solution to the problem
Implement the above server actions.

3. What the features need to be implemented to the Trio2o
to realize the solution
Add the above server actions.

Trio2o

The Trio2o provides an OpenStack API gateway to allow multiple OpenStack instances, spanning in one site or multiple sites or in hybrid cloud, to be managed as a single OpenStack cloud.

The Trio2o and these managed OpenStack instances will use shared KeyStone (with centralized or distributed deployment) or federated KeyStones for identity management.

The Trio2o presents one big region to the end user in KeyStone. And each OpenStack instance called a pod is a sub-region of the Trio2o in KeyStone, and usually not visible to end user directly.

The Trio2o acts as OpenStack API gateway, can handle OpenStack API calls, schedule one proper OpenStack instance if needed during the API calls handling, forward the API calls to the appropriate OpenStack instance.

The end user can see avaialbility zone(AZ) and use AZ to provision VM, Volume, through the Trio2o. One AZ can include many OpenStack instances, the Trio2o can schedule and bind OpenStack instance for the tenant inside one AZ. A tenant's resources could be bound to multiple specific bottom OpenStack instances in one or multiple AZs automatically.
