Why increase the timeout when the number of threads is reduced?

Hi @chia7712. I think this is not the right way to fix the test, also it's taken by someone else in the community. I guess I'll close this PR. Thanks!

Not sure if this is the right change? -- The method name literally says MultipleTimes so there seems to be an intent to add/remove threads multiple times. If we reduce this to one, it seems we are removing intended test coverage?

AdjustStreamThreadCountTest becomes flaky since this upgrade. The root cause is the timeout is not enough, for every remove and create the kafka stream thread, it takes around 10s. Should takes more on CI. I reduce the times of remove & create kafka streams and add longer timeout.
