ANN: network-manager switching from dnsmasq to resolved

Hello all,

In the last cycle we switched DNS resolution for Ubuntu
server/cloud/snappy to resolved according to the "Local DNS resolver
on all Ubuntu installs" spec [2]. This did not yet include
NetworkManager (i. e.  desktop images) as until recently there was no
DNS plugin for NM that would talk to resolved [3] and we had an old NM

Now we have 1.4 in zesty and NM grew a resolved DNS plugin, so I
backported it into our version and switched it on.

This now means that everything in Ubuntu uses the same mechanism, and
we stop having two DNS resolvers running on desktops. I gave this a
fair round of testing, but of course there is always the possibility
that this breaks stuff. If you find a regression, please file a bug
against network-manager and subscribe me.

In the worst case, these are the two commits to revert to undo this:

    these domains or on this interface only" cannot be conveyed via
