CoreDNS addon handling grew too complex

[prezha]

What Happened?

currently, we let kubeadm deploy the default coredns addon, then scale it down from 2 to 1 replica and finally patch the configmap to inject {"host.minikube.internal": hostIP} record

on a side note, i suspect that not waiting for addCoreDNSEntry() to finish could end up not adding that dns entry, if minikube exists beforehand.

all this can result in several startup "race" conditions between different components and potentially incur some delays for (benchmarking) tests that need operational dns
