Review Comment:
It seems we don't set `shouldRetry` to `false` in this test. Maybe this
method is unnecessary?

Review Comment:
As this flag is used to guard against 1) no controller and 2) kraft
controller, the naming enableEntityConfig`NoController` is a bit unsuitable.
How about `enableEntityConfigCheck`?

Review Comment:
why removing the retry? It seems that make the `testDualWriteQuotaAndScram`
unstable

Review Comment:
Maybe we can add "broker id" to the error message. That will be a useful
hint.
