Consider if to add more on KCP checks on machine status

What would you like to be added (User Story)?

As an operator, I need as much as possible info about the status of my control plane machines

Detailed Description

KCP implements checks for components status on controlled machines: API Server, Scheduler, Controller Manager, etcd

We should consider if to add more to the list of components, e.g. kube-proxy, kubelet (node). This could provide an interesting signal to catch problems that could happen during upgrades when e.g. the control plane comes up because it is implemented via static pod, but other "regular" pods scheduled on the control plane node might not come up.

Anything else you would like to add?
