Benp/new relic s3 agent

Even if we end up going with a different solution, this would be the first we roll out with. Please have a look?


I do think, for a 'next' iteration, we should look at getting more granular. Whether that is new relic or something else like splunk, would depend on what we want. If we go by naming convention, etc, we can do things like "number of objects today" etc.
