[pve-devel] [RFC/PATCH v2 manager 8/8] don't group by node in get_included_guests

Seems to simplify the handling for two of the callers and not complicate it for
the remaining one.
Including the type as well avoids the need to use the vmlist again in the
included_volumes API call.
In get_included_volumes, returning {} in the else branch was made explicit.

This is mostly a matter of taste and completely optional to the goal of the
series.
I'm not completely happy with using the '' key for the orphaned IDs and this
representation feels closer to what the callers actually need. Although, one
can argue about the caller in the vzdump API call.
And just some thought for the future: if we'd pass along the full hash to
exec_backup instead of just the IDs, the skipping of external IDs could be done
more locally.
@Aaron: Does getting rid of the grouping complicate some of the things that are
still planned with get_included_guests?
