cluster-installer - machine delete should wait for finalizers to finish before returning success

[ajitak]

When a machine CRD is marked for deletion, finalizers should delete node vm. Cluster installer should wait for finalizers to finish deleting vm whenever delete machine code path is triggered.

I had this working a while ago before we froze the prototype code in preparation for the KubeCon event, but it was rolled into work for #355 as well. I still have the code if anyone is interested in referencing it, but it will need a lot of rebasing after the recent refactoring to do proper Machine reconciliation and parallel Machine handling. For now, though, I am unassigning the issue from myself since I am now focused on Istio work.
