Our install tools like ipa-server-install, ipa-replica-{prepare,
install} may allow hostnames that do not match the requirements
in ipalib. This creates a disconnect and may cause issues when
user cannot delete hostnames created by install tools.
This patch makes sure that ipalib requirements are applied to
install tools hostnames as well.
