hosted-engine must not require vdsm-gluster and gluster-server since they require a specific channel to be enabled for having them available on RHEL.
Add a descriptive text to the setup in order to give information on how to get gluster rpms if not available.
Also disable HC support on RHEV-H where no gluster-server is available and no additional channel can be enabled.
Adding a message saying that required packages are missing should be enough to cover this. Note that this is a downstream only change.
