Original Issue: apache#11383

Describe the bug

The broker leaks direct memory when using replicated subscriptions and Key_Shared consumers. The Pulsar version 2.7.2 .

Some Netty leak detector logs were captured passing these JVM options to the broker in broker.configData.PULSAR_EXTRA_OPTS :

      -Dpulsar.allocator.leak_detection=Advanced
      -Dio.netty.leakDetectionLevel=advanced
      -Dio.netty.leakDetection.targetRecords=30

: 4 leak records were discarded because they were duplicates
: 2 leak records were discarded because the leak record count is targeted to 30. Use system property io.netty.leakDetection.targetRecords to increase the limit.

Expected behavior

Netty buffers should be released so that direct memory doesn't leak.
