Bug#491918: sitesummary: Should call hooks when entries are removed
When using hooks in sitesummary to register new hosts in a database,
update LDAP, DHCP configuration etc, it would be good to make sure the
hooks are called when an entry is removed from the sitesummary
database to have the option to remove entries from such database,
LDAP, DHCP etc. This need to be implemented. Today, removing is done
by the daily cron job using a simple find/rm combo.
