Push Build Artifacts AWS-S3

[michaeltryby]

On Appveyor it looks like you are able to associate and retrieve artifacts with a CI build.

This could be useful for solving build and testing problems on the CI server.

The best way to implement this would be to persist nrtest benchmark comparison results in a "receipt.json" file that could be parsed on failure post-test. Then the artifacts from failing tests could be easily identified and cached for retrieval.

Created Issue #17 over on the nrtest repo to discuss this with the nrtest developer @davidchall.

@michaeltryby, I think it would valuable to go ahead an push all artifacts to AWS. I'll work on that soon

@bemcdonnell I think it would be a lot easier and more straight forward to just configure the built in facility Appveyor has for saving artifacts and accessing them from the build status page.
