net: Allow for NetworkManager configuration
In cases where the config json specifies nameserver entries,
if there are interfaces configured to use dhcp, NetworkManager,
if enabled, will clobber the /etc/resolv.conf that cloud-init
has produced, which can break dns. If there are no interfaces
configured to use dhcp, NetworkManager could clobber
/etc/resolv.conf with an empty file.
This patch adds a mechanism for dropping additional configuration
into /etc/NetworkManager/conf.d/ and disables management of
/etc/resolv.conf by NetworkManager when nameserver information is
provided in the config.
