To allow the sync-all, sync-domain, sync-record, and touch-domain commands
to display errors correctly, the classes for these commands now extend the
base.DeleteCommand instead of the base.Command.
The base.Command has no formatter.
The base.DeleteCommand has the ShowOne formatter and does not show any
messages when the command is successful, but shows errors when there is
a failure.
