There is a set of commands that operate on vms.
But the API and respective fuel2 commands are
only available if 'advanced' feature is active
in 'feature_group' (from fuelmenu). In other case
Nailgun reports '(not found)'. This patch adds more
verbosity to fuel2 vms commands if 'advanced' feature
is not active instead '(not found)' responce.
