Utils scripts: ansible-ipa-[server,replica,client]-install

These are utils scripts to do a server,replica or client deployment and
undeployment using the ansible roles. A client inventory and playbook is
generated by the script which is then used with ansible-playbook.

The command line options or the normal command line installers
ipa-server-install, ipa-replica-install and ipa-client-install are all
supported also by these scripts.

Additonally to the commadn line of the normal installers it is needed to
add the fqdn of the host to be installed.

It is needed that the ansible-freeipa roles are available and also usable
by ansible.
