[Bug 1698023] [NEW] netplan does not allow a top-level 'nameservers' stanza

[Steve Langasek]

Public bug reported:

The netplan draft spec calls for 'nameservers' to be allowed as a top-
level stanza.  It is currently only implemented as a per-device
configuration.

While we've discussed that the nameserver addresses should really just
be associated with the interfaces which route to those addresses,
'nameservers' is also how you define the DNS search path as would be
included in /etc/resolv.conf.  A machine's DNS search path is not a
function of which interfaces are currently up, and needs to be globally
definable.

If we decide this is client configuration that's out of scope for
netplan, we should clarify the spec to not list 'nameservers' at the top
level.

If we decide that it is in scope, but that we still don't want to
support declaration of global nameservers just the search path, we
should fix this to be e.g. 'domain-search' at the top level.
