ipa-client-install: unilaterally set dns_lookup_kdc to True
Previously, dns_lookup_kdc was only set to True if DNS
discovery worked or if the KDC was not specified on the
command-line.
Setting dns_lookup_kdc to False would result in a hardcoded
configuration which is less reliable in the long run.
For instance, adding a trust to an Active Directory forest
after clients are enrolled would result in clients not being
able to authenticate AD users. Recycling FreeIPA servers
could prove problematic if the original hostnames are not
reused too.
Change summary:
Always set dns_lookup_kdc to True on client enrollment.
With this change, DNS SRV search will always be performed
before looking into /etc/krb5.conf realm entries.
