Fix response body format of orchestration_client to dict

'create_stack' function in orchestration_client return raw json strings.
However, in most of cases, raw json strings are not expected because it's
too hard to use. So we should do 'json.loads(body)' for the response body.
And the other apis such as {update,delete,suspend,resume} do not return a
response body in the API spec docs[1]. So we do not need to add
'json.load(body)' to the functions for now.
