We are planning to upgrade build.webkit.org to latest Buildbot, which supports only python3. We should use python3 to run transfer-to-s3 script for newer Buildbot (this script is run on the server).

Not sure the claim in the bug makes sense. buildbot being Python3 doesn't prevent it from running Python 2 processes, right? We are still running on Mojave, we can't make this change until we stop supporting it.
