Hi @alexander-demichev. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

3. Machine looks at the infra machine's status (for interruptible) and adds a label to the node.
4. Machine controller ensures the interruptible label is always present on the Node if Machine.status.interruptible is true.

Do we need to have Machine.Status.Interuptible or can we always rely on the InfraMachine status as source of truth? Are we copying this for improved UX?

I had originally suggested copying from InfraMachine to Machine, but removed it after chatting with @vincepri (trying to avoid copying when it's not required). We can update this line to say "if InfraMachine.status.interruptible is true".

One suggestion for improvement, otherwise LGTM

Based on the discussion here https://github.com/kubernetes-sigs/cluster-api/pull/3668 ([1](https://github.com/kubernetes-sigs/cluster-api/pull/3668#issuecomment-696143653), [2](https://github.com/kubernetes-sigs/cluster-api/pull/3668#issuecomment-696862994).) we can do following:
1. User creates InfraMachine with whatever spec field(s) are required for that provider to indicate it's interruptible.
2. Infra provider sets InfraMachine.status.interruptible=true
3. Machine looks at the infra machine's status (for interruptible) and adds a label to the node.

This might be clearer? I feel like we can probably combine 3 + 4, WDYT?

Suggested change
3. Machine looks at the infra machine's status (for interruptible) and adds a label to the node.
3. Machine controller looks at InfraMachine.status.interruptible and ensures a label is set on the node if it is true.
