Description

Sometimes we want to define server properties for all test cases, and using `BeforeEach` to modify the `ClusterConfig` is the only way. The side effect is that the IDE does not like the style since IDE can't recognize custom ParameterResolver of `ClusterConfig`.

The alternative is that we can take `ClusterInstance` from constructor first, and then we modify the inner `ClusterConfig` in `BeforeEach` phase. However, that may confuse users about the life cycle of "configs".

In short, I prefer to define the server property by `ClusterTestDefaults`. It already includes some server-side default property, and we can enhance that to deal with more existent test case.
