Motivation
FastThreadLocalStateCleaner is used in apache/pulsar tests to clean up state stored in thread local fields using Netty's FastThreadLocal. This solution was added in #10195 to reduce test flakiness caused by state carried on from one test to another.
This change included in 4.1.75.Final added the logging when the thread local state is accessed from another thread. This logging clutters the test run logs and therefore it should be eliminated.
Pulsar was upgraded to Netty 4.1.76.Final in #15212.
