Test and Documentation Plan

It looks like the previous assertWarnAborts method call may create a warn in the metrics under certain conditions. Making sure that we have a histogram checkpoint after disabling the warn tracking ensures that we are in the expected state before executing the non failing query.

Description

The test org.apache.cassandra.distributed.test.trackwarnings.LocalReadSizeWarningTest#failThresholdSinglePartition seems to be flaky.

It was discovered during CASSANDRA-17195 with this CI run.

The failure can be reproduced running the test repeatedly for trunk, as it can be seen here.
