4a4c545 KDC autodiscovery may fail when domain is not realm

    KDC autodiscovery may fail when domain is not realm
    
    When ipa-client-install autodiscovers IPA server values it
    doesn't fill the fixed KDC address to Kerberos configuration
    file. However, when realm != domain or the autodiscovered values
    are overridden, installation may fail because it cannot find the
    KDC.
    
    This patch adds a failover to use static KDC address in case when
    such an issue occurs.
