samba-tool: Create NIS enabled users and unixHomeDirectory attribute

Allow to create NIS enabled user accounts via 'samba-tool user add'.

To create NIS enabled accounts, the parameters
--uid-number=, --login-shell=, --unix-home=, --gid-number=
are mandatory. Because we didn't had a parameter to set unixHomeDirectory
yet, this patch also adds this feature.

'unixUserPassword: ABCD!efgh12345$67890' is added by default, when you
enable NIS on an account in ADUC. The same we do in samba-tool.

See: https://bugzilla.samba.org/show_bug.cgi?id=10909
