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
