test:added tests for config changes

[purnimavenkatasubbu]

- What I did Added tests for stats:13(Access log compaction), stats:14 (Commit log compaction) - How I did it By setting the compaction job to run every 1 minute by using the config: set verb and then updating the keys multiple times.

- How to verify it acesslog_compaction_test.dart and commitlog_compaction_test.dart should pass.

- Description for the changelog

Hey @purnimavenkatasubbu - there are timing issues in the tests you added. I'll think over the weekend about how to resolve these
