ECS reflects changes to the ghost service name.

            When changing the name of a ghost service, the ECS
            records are properly updated, so that when changes
            are committed the resulting service is given the desired
            name.

            This also includes ghost unit names.

            QA:
            Use the mv flag.
            Drag a service and click commit: the service and its
            unit should be deployed as usual.
            Now drag a new service, and use the inspector to rename it.
            Open and close the service inspectore multiple times to ensure
            the inspectore reflects the new service name.
            Open the deployer panel to show the changes: both the service and
            the unit have the correct customized name.
            Switch to the machine view and check the service units is also
            renamed.
            Commit the changes: the deployment summary shows the proper names.
            When the ghost is deployed, the resulting service should
            have the desired name.
