Running "openstack service set <id> --description="
will throw an error [1].
The error occurs because the request to Keystone must include any
of enabled, name or type to satisfy the minProperties of the patch
request.
This patch always sets the --name parameter when calling the openstack
command so that we satisfy this requirement.
