Add domain and no-ntp options to ipaclient

Two options have proven useful for deployers.
--domain: To specify the IdM DNS domain in cases where the client is
  not in the same DNS domain as the IdM server
--no-ntp: To ensure that the idm-client-install does not change the
  NTP settings when they have already been set by puppet.

The patch adds both these options.
