k8s-certs-renew.sh script hangs

[jijisa]

Describe the bug

k8s-certs-renew.sh script has a problem with the current burrito.

It hangs after this line.

## Waiting for apiserver to be up again ##

This is the problem.::

until printf "" 2>>/dev/null >>/dev/tcp/127.0.0.1/6443; do sleep 1; done

The kube-apiserver does not listen to 127.0.0.1 so it hangs.

To Reproduce
Steps to reproduce the behavior:

1. Run k8s-certs-renew.sh script

Versions (please complete the following information):

• OS: Does not matter
• Burrito: 2.1.2
