The import line of ansible_ipa_client was not correct and used a test
version of the binding that is not possible anymore due to the move of
the module_utils directories into the specific role locations.
The new module ipaclient_setup_ntp to configure and sync time with the NTP
server has been added. The irregular setting ipaclient_ntp has been removed.
The ipaclient_setup_ntp module is using either the new sync_time call or
for compatibility with older FreeIPA versions synconce_ntp.
The reference for ipaclient_ntp in REPLICA.md has been removed also.
This also fixes#55.
