The hidden replica support introduced some incompatible changes to replica
deployment. The methods find_providing_server and find_providing_serves
have been moved from ipaserver.install.service to ipaserver.masters.
Additionally the host_name argument for find_providing_server is a list
now. This breaks existing ipareplica Ansible modules ipareplica_prepare
and ipareplica_enable_ipa.
With the changes for IPA enablement in the replica installer it is not
possible anymore to enable the IPA server in the same way as in the
server deployment.
The new module ipareplica_enable_ipa has been added and the link for
ipaserver_enable_ipa has been removed.
