Thomas Woerner 397acc01db ipaclient: Make krb5 DNS lookup possible in cluster environments
krb5 DNS discovery was not possible in cluster environments as the server
list from groups.ipaserver was used all the time. DNS discovery is though
only used if no servers are given.

The new setting ipaclient_no_dns_lookup has been added to make sure that
DNS lookup is used in the first place and can be disabled easily with this
setting. There is also a new way to override servers per client in the
inventory file with ipaclient_servers.

Two new settings have been added:

ipaclient_no_dns_lookup (bool, default: no)
  Set to 'yes' to use groups.ipaserver in cluster environments as servers
  for the clients. This deactivates DNS lookup in krb5.

ipaclient_servers (list of strings, default: undefined)
  Manually override list of servers for example in a cluster environment on
  a per client basis. The list of servers is normally taken from from
  groups.ipaserver in cluster environments.
