Merge #1699

1699: Build docker image from existing release binary upon release r=mergify[bot] a=thomaseizinger

Resolves #1425.

I am not using GitHub actions as mentioned in the ticket but instead do it as part of the release step in the CircleCI build. This way we don't need to figure out how to wait for the proper event when the binary gets attached.

Need to remove the dockerhub build once this is merged.
