I manually verified this works by adding a .retain() call in org.elasticsearch.transport.netty4.Netty4MessageChannelHandler#channelRead.

* Enabled advanced leak detection when loading `EsTestCase`
* Added custom `Appender` to collect leak logs and check for logged errors in a way similar to what is done for the `StatusLogger`
* Fixes elastic#20398

The approach is great! I left one comment, but this LGTM and doesn't need another review.
