k8s 1.27: remove defaults for kube-api-burst and kube-api-qps

Description of changes:

Removes the default value for kube-api-burst and kube-api-qps

In K8s 1.27, the defaults were increased kubernetes/kubernetes#116121 to 50/100 which is even higher, so we can rely on those defaults now.

Testing done:

cargo make \
  -e BUILDSYS_VARIANT="aws-k8s-1.27" \
  -e BUILDSYS_ARCH="x86_64" \
  unit-tests

Looks good, pending some additional testing results.

Thanks!

Tested changes in a 1.27 node. Node joins cluster successfully and no longer explicitly sets defaults for kube-api-burst and kube-api-qps
