Move PKINIT configuration to a later stage of server/replica install
    
    This is to ensure that we can request PKINIT certs once all the
    following requirements are in place:
    
        * CA is configured or PKCS#12 file is provided
        * LDAP, KDC and Apache are configured and the master role is thus
          completed and enabled
