BacklogQuotaManagerTest is flaky. The testConsumerBacklogEvictionTimeQuota test method fails sporadically.

example failure: https://github.com/apache/pulsar/runs/4942921605?check_suite_focus=true from https://github.com/apache/pulsar/pull/13950

This issue doesn't seem to be solved.

Here is another failure after #14000 gets merged.
