Distribution packaged ntpd has servers preconfigured in ntp.conf so
there's no point in trying to add them again during FreeIPA server
installation.
Also fix the code to always put fudge line right after the local server
line as required by ntpd.

Set explicitly krbPwdPolicyReference attribute to all hosts (entries in
cn=computers,cn=accounts), services (entries in cn=services,cn=accounts) and
Kerberos services (entries in cn=$REALM,cn=kerberos). This is done using DS's
CoS so no attributes are really added.
The default policies effectively disable any enforcement or lockout for hosts
and services. Since hosts and services use keytabs passwords enforcements
doesn't make much sense. Also the lockout policy could be used for easy and
cheap DoS.

In client plugins make sure the api_version is 'inherited' from server command
that is internally called. Otherwise the api_version is obtained from client
API instance. When calling server command from client command 'version' is
passed in options and it overrides the right one. Server then refuses to handle
such call.

When client comunicates with server that doesn't support 'schema'
