Thx for the feedback. Currently, we don't support `call` on certain height. This feature will be supported in our [archive mode](https://github.com/iotexproject/iotex-core/issues/2847). Our dev team is working on it.

All unmoved config definitions in config.go directly or indirectly import action package. However, if the config structs in config.go are moved to their responding package, there will be a loop...

Dependency would be decoupled after the pr https://github.com/iotexproject/iotex-core/pull/3035 is merged

fixed by https://github.com/iotexproject/iotex-core/pull/3503

The trie is redesigned in the prs ( #3194, #3193 ). The test is to be added after the change is merged.

@huof6829 could you help fix the ci failure?

1. move the default config of consensus to `consensus` pkg then, default value could be imported in `config.go` like https://github.com/iotexproject/iotex-core/blob/d6eaa2efddfc6691b0eebcb5a0d2a4c68f444597/config/config.go#L185 2. `config.go` should be put under `./consensus` folder.

@LuckyPigeon could you help the failure of test?

Could this format of logs be indexed?
