Add behavior example for anchor refresh propagation

Without this patch we don't have a spec test to make sure the anchor
resource type passes notify events along.  This patch addresses the
problem by using RSpec Puppet to build a catalog, apply the catalog,
then pull a resource out of the transaction and make sure the resource
was triggered.
