WICD best-effort cleanup if services ConfigMap is not found

Description

WICD uses the services ConfigMap tied to the desired version annotation to deconfigure a node. If the expected services ConfigMap cannot be found for any reason, a best-effort cleanup should occur to remove:

• Windows services with the OpenShift managed tag (and any dependent services)
• all services in the latest-created services ConfigMap, if one exists

Engineering Details

• services in the latest-created ConfigMap should be stopped in reverse order of creation (using priority values)

Acceptance Criteria

• If the expected ConfigMap is missing, the WICD cleanup command will safely removes
  • any remaining Windows services with the `openshift-managed` string in their description
  • all services in the most recently retrievable services ConfigMap
• When ran with the `--preserveNode` argument, the Node object will not be deleted
• No change in behavior if the expected ConfigMap is found
