Reduce transfer volume to Papertrail

We're sending more data to Papertrail than we can afford, so I'm

re-enable the HTTP logs but filter out static assets using
Papertrail's filtering features.

Added Resque queue for Zapier REST hooks, which needs to happen before reports jobs.
Enable the resque-scheduler recipe.
Tune collectd daemon to stop notifications from the Resque utility instance.
Apparently there are times when that code executes and the node name is nil.  No idea how that works...
