Introduce ipa control script that reads configuration off ldap

This replace the former ipactl script, as well as replace the current way ipa
components are started.

Instead of enabling each service in the system init scripts, enable only the
ipa script, and then let it start all components based on the configuration
read from the LDAP tree.
