[Samba] Demote/Promote Samba DC

[Stefan Bellon]

Not sure whether this has anything to do with it ... but I demoted our
old Samba 4.2 server yesterday from the domain as well.

While "samba-tool domain demote -Uadministrator" worked fine and
reported success, in the DNS there were still ~20 records referring to
that old DC. I stopped the old Samba 4.2, removed the BIND9 DLZ
integration on that old DC, restarted all BIND instances (also
those on the newer Samba 4.13.5 DCs) ... still, all the records
remained.

I ended up starting DNS tools on Windows and opened the whole tree,
went through the entries one by one and deleted all that were still
referring to the old DC (except of course the actual A and AAAA
records).

I think, "domain demote" only takes care of part of the demotion?
