add operational_attributes that inherited classes can set them
get identifier value from object

+   see U(https://developer.hashicorp.com/consul/api-docs/agent/check).

+   tell if the data supplied with ansible represents a change to a check. As a
+   result this does not attempt to determine changes and will always report a
+   changed occurred. An API method is planned to supply this metadata so at that
+   stage change management will be added.
