The two unhealthyConditions timeouts were fixed in the template at 30s for `Ready=Unknown` and 300s for `Ready=False`, and both are too tight for a worker joining on a loaded host. `Ready=Unknown` is what the node lifecycle controller writes when a kubelet stops reporting, on a grace period of its own, so 30s on top of that deleted the VM of a guest that had merely stopped being scheduled for a stretch, before it had a chance to answer again. And `Ready=False` is the condition a registered Node holds until its CNI is up, so 300s was the entire budget a first boot got for the CNI rollout to reach it -- a worker deleted mid-rollout takes the rollout with it and its replacement starts over. Move both to values, defaulting to 5m and 10m. The remediation of a worker that is genuinely dead is correspondingly later, which costs less than it appears to: Pods leave an unreachable Node on the node lifecycle controller's taint-based eviction and the toleration that carries, not on either of these timers.
