Hyper-V: After live migration succeded, the only instance dirs on the source host are not cleaned up

[Claudiu Belu]

After the instance has succesfully live migrated to a new host, the instance dirs on the source host should be removed. Not doing so can cause useless clutter and used disk on the source node. This issue is more notably when hundreds, thousands of instances were deployed to a host.
