Update proxy documentation for AIO

This change adds in information about overriding the dns entries
that can end up overwriting the existing ones in resolv.conf
and resulting in a lack of network connectivity when deploying
AIO behind a proxy.

By default, this installation will use Google DNS Server IPs (8.8.8.8, 8.8.4.4)
and will update resolv.conf as a result. If those IPs are blocked by the proxy,
this will overwrite the original DNS entries and result in the inability to
connect to anything on the network behind the proxy. These DNS nameserver entries
can be changed by updating the ``external_dns_nameservers`` entry in this file:
.. code-block:: bash
openstack-helm-infra/tools/images/kubeadm-aio/assets/opt/playbooks/vars.yaml
It is recommended to add your own existing DNS nameserver entries to avoid
losing connection.
