Please review and provide your feedback.

-Thanks

Thanks Kishan for your input.

Since we will now rely on Events Framework feature to publish events that could be used by
admins to maintain data sync between regions , I have created test plan for this feature-
https://cwiki.apache.org/confluence/display/CLOUDSTACK/Events+Framework+Test+plan .
This test plan addresses only a part of Event Framework feature that is needed by AWS regions
feature for achieving data sync of Account/Domain/User objects between regions.
Please provide your feedback.

-Thanks
Sangeetha

[KK]  Forwarding to owner region should be removed. Data sync is external to CloudStack.

[KK]  When account/domain is deleted all resources will also be deleted.

[KK] Since data sync is external to CloudStack, we don't need the notion of owner region.

[KK]  getUser API is for components like object-store to authenticate and get account information

[KK]  I've added the response parameters to the spec.
