The webhook URL is simply a HTTP endpoint to which ceilometer will send
a POST request when the alarm fires.

If you want to trigger the creation of an instance when the alarm fires,
that sounds exactly like what Heat autoscaling already provides (in that
case, the webhook endpoint is already provided by Heat, so you don't have
to set anything up from scratch).
