lists/centaurus/samba has been changed to use Samba as a file server.

Made at the request of Evgeny Sinelnikov <sin@altlinux.org>
This patch was co-authored by Anton Abramov

Network interface management system:
- NetworkManager daemon by default
- Systemd network configuration daemon

These have been:
- taken from x86_64 server iso (in substituted form);
- checked against m-p-d where needed;
- renamed from centaurus-* to centaurus/*;
- updated with s/samba-server/samba/;
- archdep bits adjusted for m-p-d/m-p syntax difference;
- amended with some tester feedback based additions included;
- pruned regarding p9/branch packages availability.
