in the Storage/Status API call we have a 'enabled' param which had no
effect because storage_info only returned enabled one way or the
other.
This affected also `pvesm status` which uses the Storage/Status API
call.
So push also disabled storages to the info array but only activate
and get their status when thei are enabled.
