Title: Sending varnish logs to logstash

Formatted varnish log output to logstash JSON format. Also had to setup
a filter to convert varnish timestamp to iso8601. The version of varnish
we are using (3.2) doesn't support specifying a time format and 3.4
hasn't been released yet.

Lumberjack ships the logs to logstash.
