Identify Node to be drained/deleted using reference in Machine object #63

Open dlipovetsky opened 6 years ago

dlipovetsky commented 6 years ago

Right now the node is identified by invoking hostname -f on the host, but this only works coincidentally. Once https://github.com/platform9/ssh-provider/issues/17 is fixed, use the Node reference.

Every node must have a unique MAC and product ID [0].
