This uses edit_resource to add a notification in the block storage
apache configuration when it gets updated. This is a workaround due to
the fact we are using a version of the apache2 cookbook that is still
using definitions and cannot add notifications with definitions.
This will be removed in the Stein release when we migrate to the newer
apache2 cookbook which uses proper resources.
