Autoreject duplicate results

[obbardc]

For pull requests which have the same results (e.g UUID in the filename) as existing results in the database, we should close PRs and issues.

@htejun is UUID in filename a suitable collision detection method?

In this case, rejection really means closing of issue, PR , deletion of files in bucket & branches.

Possibly there could be a nightly CI run which triggers this.

I don't know where there UUID in the filename is coming from. I think it might make sense to add a signature in the result json file itself for reliable detection - ie. let the json file carry its own signature as its ID. What do you think?

Looks like that md5sum is currently the md5sum of the uploaded data. we can initially reject on that, before even processing the result.
