Is this a bug fix or adding new feature?

Bug fix

What is this PR about? / Why do we need it?

Handle deleted Node case in hook

When the Node object does not exist, the existing hook returns an error. Instead, in this case, assume the node is being drained and proceed with the hook. Partially solves #1955

Add support for CAS taint

Similar to Karpenter, cluster-autoscaler has its own custom taint it uses when draining nodes. Add it to the hook's drain detection logic.

What testing is done?
