Remove kubedns and dnsmasq. Move dns_late phase after apps (#4406)

Browse Source 
Both kubedns and dnsmasq modes are long not maintained.
We should run dns_late steps at the end because sshd
makes DNS lookups during Ansible run and has 2s timeouts
for each failed lookup trying to connect to coredns before
it is ready.
