### Describe the feature

We should include `NettyMemoryMetrics` to enhance memory metrics for `PooledByteBufAllocator`. https://github.com/apache/spark/blob/master/common/network-common/src/main/java/org/apache/spark/network/util/NettyMemoryMetrics.java

Start by reading Spark's NettyMemoryMetrics implementation at the linked common/network-common/src/main/java/org/apache/spark/network/util/NettyMemoryMetrics.java and compare how this project creates its PooledByteBufAllocator for clients and servers. Done means equivalent memory metrics are included for both Netty client and server allocators.
