autobuild and dnspython

[Noel Power]

Hi,

I was trying to push my branch to autobuild, I'm running into a problem
with dnspython [1], it appears we have an intree version in third_party
(that isn't used in gitlab CI) The version is in samba seems woefully
out of date, what is the procedure here?, do I need to try and port the
failing bits to python3 (and that may not be trivial at all)

I am not aware of the history here but surely this package isn't
something we need to be hanging on to is it ? do we have some real samba
specific stuff in there. It would be great if the autobuild machine
could just use system python/python3 dnspython packages and/or drop that
completely from thirdparty (something tells me it's not going to be that
easy :///)

thoughts,

Noel
