stone-stg-host: remove host-operator subscription (#7434)

We can remove host-operator from stone-stg-host, since we will no longer
be needing it for namespace management.  The first step to do this is to
remove the Subscription from stone-stg-host so that the deployments can
be safely scaled to zero.
