Document 2.53 behavior for compute service list/delete

With compute API microversion 2.53, nova-compute services
can only be deleted with the ID as a UUID to uniquely identify
the service in a multi-cell deployment. This documents that for
the "compute service delete <service>" argument. The description
of the "compute service list" command is also updated to mention
that the ID can be retrieved as a UUID using 2.53 or greater.
