[03e162b3] Update OWNERS
[c7b00cae] Use tar+register instead of copy/slurp for distributing tokens and certs

Related bug: https://github.com/ansible/ansible/issues/15405

Uses tar and register because synchronize module cannot sudo on the
remote side correctly and copy is too slow.

This patch dramatically cuts down the number of tasks to process
for cert synchronization.
[2778ac61] Add new var skip_dnsmasq_k8s

If skip_dnsmasq is set, it will still not set up dnsmasq
k8s pod. This enables independent setup of resolvconf section
before kubelet is up.
