2) Introduced responseObject field in @Implementation for all apis. This field contains information about the response object class, so we can used it for generating API documentation.
* Implement callCreate() and execute() methods in apis extending BaseAsyncCreateCmd (example - CreateVolumeCmd)
* Implement execute() method in apis extending BaseCmd and BaseAsyncCmd (example - deleteVolumeCmd and deleteUserCmd)
We no longer need createMethod(), method(), manager() fields in @Implementation annotation, cleanup has to be done.
2) Moved Account/User related methods to AccountManagerImpl. Methods are exposed via AccountService interface.
3) Enhanced exception handing for Api calls.
4) Created ConfigurationService interface, all Api config methods are exposed via it.
* Changed response type for DeleteDomain and DeletePreallocatedLun commands to SuccessResponse
* Implemented small tool (ApiXmlDocReader) for comparing api commands of different product versions.
The previous behavior had the JSON response from the command embedded into the queryAsyncJobResult response as a string rather than a JSON object which prevented the client from being able to read the response. With this new behavior an actual JSON object should be returned which can then be parsed on the client side.
