Revert using custom built logging jar for now. (#4945)

As title.

Turns out this requires GCS access. It's not practical to give it to everyone. Revert this for the time being while we properly publish to maven.

This will affect Kube clusters built locally attempting to log to S3. This will not affect the already published version.
