e7e0e82f43 Fallback to default resolver if no nameservers 
Current design expects users to define at least one
nameserver in the nameservers var to backup host OS DNS config
when the K8s cluster DNS service IP is not available and hosts
still have to resolve external or intranet FQDNs.

Fix undefined nameservers to fallback to the default_resolver.

bab6ec8477 Fix resolvconf 
Do not repeat options and nameservers in the dhclient hooks.
Do not prepend nameservers for dhclient but supersede and fail back
to the upstream_dns_resolvers then default_resolver. Fixes order of
nameservers placement, which is cluster DNS ip goes always first.

0f0858703b Fix reverse umount in reset role 
The Jinja2 filter 'reverse' returned an iterator instead of a list,
resulting in the umount task to fail.

Intead of using the reverse filter, we use 'tac' to reverse the output
of the previous task.

8679f10f71 Rework DNS stack to meet hostnet pods needs 
* For Debian/RedHat OS families (with NetworkManager/dhclient/resolvconf
  optionally enabled) prepend /etc/resolv.conf with required nameservers,
  options, and supersede domain and search domains via the dhclient/resolvconf
  hooks.

* Drop (z)nodnsupdate dhclient hook and re-implement it to complement the
  resolvconf -u command, which is distro/cloud provider specific.
  Update docs as well.

* Enable network restart to apply and persist changes and simplify handlers
  to rely on network restart only. This fixes DNS resolve for hostnet K8s
  pods for Red Hat OS family. Skip network restart for canal/calico plugins,
  unless https://github.com/projectcalico/felix/issues/1185 fixed.

* Replace linefiles line plus with_items to block mode as it's faster.
