nsupdate: add server FQDN and GSS-TSIG support (#11425)

* nsupdate: support server FQDN

Right now, the server has to be specified as an IPv4/IPv6 address. This
adds support for specifing the server as a FQDN as well.

* nsupdate: support GSS-TSIG/Kerberos

Add support for GSS-TSIG (Kerberos) keys to nsupdate. This makes life
easier when working with Windows DNS servers or Bind in a Kerberos
environment.

Inspiration taken from here:
https://github.com/rthalley/dnspython/pull/530#issuecomment-1363265732

Closes: #5730

* nsupdate: introduce query helper function

This simplifies the code by moving the protocol checks, etc, into a
single place.

* nsupdate: try all server IP addresses

Change resolve_server() to generate a list of IPv[46] addresses, then
try all of them in a round-robin fashion in query().

* nsupdate: some more cleanups

As suggested in the PR review.

* nsupdate: apply suggestions from code review
