Okay, since TCM_VHOST is experimental in kernel, as we are in feature
freeze for Groovy, I'm going to cap the missing features from targetcli
so end user does not experience failures from the UI. This bug can serve
as a future guidance in enabling those options (specially TCM_VHOST).

instead of enabling the feature.
