/kind feature New functionality.

If there are not enough worker-nodes, then you get errors like this:

❯ k get -o yaml -n kube-system deployments.apps  konnectivity-agent
....

  availableReplicas: 2
  conditions:
  - lastTransitionTime: "2023-08-15T07:45:46Z"

This PR reduces the number if mininmal available pods to 2.

This means the above error still appears in clusters with one worker node.
