Fix object storage bulk middleware client return value
All service clients methods return their response wrapped in
ResponseBody, ResponseBodyData or ResponseBodyList.
But object storage service clients were left out of this
because response from object storage APIs are not same way other
service return. Some APIs return is as string etc.
This commit makes bulk_middleware_client to return ResponseBodyData
object with consistency to other service clients.
This is step to move these clients to lib.
Partially implements blueprint consistent-service-method-names
