[Samba] Samba upgrade...v4.7.6->4.16.x

[Norbert Hanke]

Some upgrades while skipping certain major versions work, some do not.

With this big step across many versions it's much less troublesome to
demote the existing [least important] DC, do the upgrade and then join
the DC again using the fresh installed binaries.

regards,
Norbert

(It's a VM, and I have snapshots, so it's easy to go back, if I have do, but I'd like to avoid as many mistakes as possible...)
