Submits a request to the host manager of the cluster in use: once, with no fail-over.The generated host manager endpoints (`/admin/add/host`, `/admin/alter/host`, `/admin/remove/host`, `/admin/show/alerts` and `/admin/switchover`) come through here. They name hosts and ranks within the cluster they are sent to, so a failure goes back to the caller rather than replaying the operation on another cluster.
