FreeIPA's `ipasam` module to Samba uses gethostname() call to identify
own server's host name. This value is then used in multiple places,
including construction of cifs/host.name principal. `ipasam` module
always uses GSSAPI authentication when talking to LDAP, so Kerberos
keys must be available in the /etc/samba/samba.keytab. However, if
the principal was created using non-FQDN name but system reports
FQDN name, `ipasam` will fail to acquire Kerberos credentials.
Same with FQDN principal and non-FQDN hostname.
Also host name and principal name must have the same case.
Report an error when configuring ADTrust instance with inconsistent
runtime hostname and configuration. This prevents errors like this:
[20/21]: starting CIFS services
ipa : CRITICAL CIFS services failed to start
where samba logs have this:
[2017/03/20 06:34:27.385307, 0] ipa_sam.c:4193(bind_callback_cleanup)
kerberos error: code=-1765328203, message=Keytab contains no suitable keys for cifs/ipatrust@EXAMPLE.COM

adtrustinstance will now use parent's methods to retrieve keys for CIFS
principal. Since the keys are appended to the host keytab
(/etc/krb5.keytab) we need to make sure that only the stale CIFS keys
are purged from the file and that we do not re-set its ownership.

The Service class now accepts keytab path and service name part of Kerberos
principal as members. Kerberos principal is turned into a property computed
from service prefix, FQDN and realm. the handling of Kerberos principals and
keytabs in service installers was changed to use class members instead of
copy-pasted constants. This shall aid in the future refactoring of
principal/keytab handling code.
