ntp_server and ntp_pool are now provided to ipareplica_test. A conflict
test with no_ntp has been added from the normal installer.
Also added are references to options.password and options.dm_password, but
these are commented out and not used or provided to the module.
Proper ntp_servers and ntp_pool tests are needed still.
The support for external cert files is not complete yet.
Please have a look at the example inventory file inventory/hosts.replica and
also the install and uninstall playbook files install-replica.yml and
uninstall-replica.yml
