Also log RPC request on error

[bkchr]

It would be nice to know what RPC request lead to an error like:

Error handling request: 'RpcError: -32008: Response is too big: Exceeded max limit of 1048576

If possible, the error log should also contain the RPC request.

From what I looked into this would be pretty straightforward for the HttpProvider. That being said - the WsProvider would be somewhat of a challenge and would take a bit of work to get enhanced with the method as part of the error message.

Happy to add this to the roadmap as resources are going to start freeing up soon.

On another note - there is always the ability to track the WS logs when setting the env var DEBUG=api-ws for polkadot-js. This will atleast give all the insight needed to track the id of the rpc request that caused the error.
