Cédric Jeanneret 916b043710 Ensure NetworkManager doesn't override /etc/resolv.conf 
Until now, whenever NetworkManager gets reloaded/restarted/lease
refresh, it would override the /etc/resolv.conf file with the
nameservers and related it gets from the network.

This patch ensures this won't happen ever again.

Note: this is a corrected version of
I92bc12b8f712e28962d24dd6474cfce22b81222c
that was reverted due to indentation + use of ConfigParser issues.

nodepool-base

Tasks to deal with image metadata and other Nodepool cloud specific tweaks.

Name resolution

The image should have the unbound DNS resolver package installed, the nodepool-base element then configures it to forward DNS queries to:

NODEPOOL_STATIC_NAMESERVER_V4, default: 1.0.0.1 NODEPOOL_STATIC_NAMESERVER_V4_FALLBACK, default: 8.8.8.8.

If NODEPOOL_STATIC_NAMESERVER_POPULATE_IPV6 is set to 1 then the following two servers will be configured as forwarders too

NODEPOOL_STATIC_NAMESERVER_V6, default: 2606:4700:4700::1111 NODEPOOL_STATIC_NAMESERVER_V6_FALLBACK, default: 2001:4860:4860::8888

Note externally setting either of these values implies NODEPOOL_STATIC_NAMESERVER_POPULATE_IPV6=1
