is there a reason you have forked benchmarking completely? We are changing it too much?

[xlc]

Mainly most of Acala pallets have tight coupling and it is impossible to write generic benchmark tests. We need to access the Runtime struct. As result, many of our benchmarks are ends up in the runtime https://github.com/AcalaNetwork/Acala/blob/master/runtime/mandala/src/benchmarking/cdp_engine.rs

One specific example is that our Balance type is not generic https://github.com/AcalaNetwork/Acala/blob/b813733865b875176c7c9336c5515397c65ab90d/modules/cdp-engine/src/lib.rs#L158
