[BewareMyPower]

Is your feature request related to a problem? Please describe.

• The most recent successful test (fa94761) took 43 min (tests 40 min): https://github.com/streamnative/kop/runs/3952242908?check_suite_focus=true
• The most recent failed test (17102ac) took 46 min (tests 43 min): https://github.com/streamnative/kop/runs/3952474870?check_suite_focus=true
• Before some commits (3335f09), it took 33 min (tests 30 min): https://github.com/streamnative/kop/runs/3846689255?check_suite_focus=true

Describe the solution you'd like
Some tests are unnecessary, like tests for all formatters. And there're some tests that could be speeded up.

Describe alternatives you've considered
