S3 Publisher can't be configured to prevent overwriting existing uploads if they exist

Pre-flight checklist

• [X] I agree to follow the code of conduct that this project uses.
• [X] I have searched the issue tracker for a feature request that matches the one I want to file, without success.

Problem description

At the moment it's possible for an artifact to be uploaded over top of previous artifact.

Proposed solution

It would be fantastic if the s3 publisher was more customizable. Either allowing middleware to be supplied directly by the user, or by having a config option that supplies the If-None-Match: * header to s3 when uploading.

Alternatives considered

In the key resolver step you can make a request to check if something is already on the server… Though that requires synchronously executing an http request.

Downsides:

• Complexity
• Race condition
