smb.conf now sets state and cache directory, then includes the registry.
This also allows us to write the final smb.conf before importing
remaining settings into the Samba registry.

There is no recommended value but for IPA DC we can limit with 1000
concurrent connections from unrelated clients.

Implicit idmap configuration in Samba was changed in Samba 4.7 to always
require range definition. A default ('*') idmap configuration lacks any
range and thus is marked by testparm utility as invalid one.
Since we do not expect Samba allocating any IDs, idmap configuration
needs to be set in a such way that it is correct from Samba side and is
effectively disabling any allocation on those domains that we don't need
to handle.
Note that 'idmap config <domain> : range' parameter accepts range in a
special format with spaces 'begin - end', so we have to keep the
formatting of the range exact.

Samba 4.5 does not allow to specify access mode for the keytab (FILE: or
WRFILE:) from external sources. Thus, change the defaults to a path
(implies FILE: prefix) while Samba Team fixes the code to allow the
access mode prefix for keytabs.
On upgrade we need to replace 'dedicated keytab file' value with the
path to the Samba keytab that FreeIPA maintains. Since the configuration
is stored in the Samba registry, we use net utility to manipulate the
configuration:
net conf setparm global 'dedicated keytab file' /etc/samba/samba.keytab

Samba just needs the cifs/ key on the ipa server. Configure samba to use a
different keytab file so that we do not risk samba commands (net, or similar)
to mess up the system keytab.
