This is needed so that we can actually update the given topology with
the updated data after a successful claim.
Deleting it will also be needed when we actually make the resize work
properly for instances with NUMA topology, so we add it here as well.
We do not expose the new InstanceNUMATopology methods as @remotable to
avoid having to bump the object version thus making this an easier
backport target. This is OK since they are only called from
Instance.save() which is @remotable, and can be trivially made remotable
should this be needed later (causing a version bump that need not be
backported).
