This ended up being added in HBASE-27170
> Consider adding ResourceLeakDetector to RefCnt

> Reporter: Bryan Beaudreault
> Priority: Minor
>
> In my quest to figure out HBASE-27170, I ended up adding ResourceLeakDetector
> to RefCnt in my local fork. This immediately reports the leak to the logs,
> making it hard to miss. ResourceLeakDetector is already active in the netty
> layer, and the default state is designed to be very low overhead. We could
> add it directly to RefCnt, or make it further configurable if we're concerned
> about performance. Either way it's good to have and document, to aid future
> leak investigations.
