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

SASL bind callback due to refactoring was referencing local variable which
didn't exist all the time. Fix that by including a copy of service principals
into ipasam long term private struct.
Rework ccache handling to avoid re-initing every time callback is called
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.
