Fix Version/s: (was: 4.0.0)
> [FlightRPC][Java] Allow using a per-call Arrow allocator
> --------------------------------------------------------

> We've been running into issues with Flight and gRPC leaking direct memory at
> scale. One thing we'd like to do is have a (child) allocator per DoGet/DoPut
> call, so we can more accurately track memory usage. We have a candidate
> implementation that is rather messy, but can be upstreamed as part of
> flight-grpc.
> This also requires changes to _ensure_ all Arrow resources are cleaned up
> before we notify gRPC that the call has finished.
