Can we now get rid of serde_json dependency?

serde_json is still used for all to_string serializations

JSON serialization/deserialization of `i128`/`u128` can only be supported when the `arbitrary_precision` feature enabled. But `arbitrary_precision` numbers don't work with `serde(tag = ..)` and `serde(flatten)` syntax (serde-rs/json#505), as a result, the deserialization of structures in `jsonrpc-core` will be error. Fortunately, the crate `jsonrpc-core` provides a workround(paritytech/jsonrpc#521). Although this workround will cause more extra serialization/deserialization work, but I think it's worth it.

serde deserializes incorrectly when arbitrary precision is enabled.
fixes #520
The workaround is to deserialize into
ValuebeforeClientResponse. This is gated under the featurearbitrary_precisionin core-client andtransports.
