Custom Provider with #parity_listStorageKeys

[Latrasis]

Context

When debugging or accessing storage within an account, it is valuable to see all the storage keys used within an account's state tree. Currently this is solved with injecting logs into a contract, this however makes development cumbersome and is not possible with already compiled contracts.

Expected Behavior

The Parity JSONRPC Api includes #parity_liststorageKeys which lists all used storage keys of an account.
This is incredibly useful for debugging purposes and can be opt-in with a flag. --fat-db

Current Behavior

Ganache-core currently does not provide any way to list account storage keys when debugging

Possible Solution

Include a custom provider which exposes a subset of parity json-abi calls for debugging, starting from: #parity_liststorageKeys.

Environment

• Version used 2.1.0
• Operating System and Version: WSL Bash

Hey @Latrasis! This does sound like an interesting feature, but I think you could use debug_traceTransaction and/or use the Truffle Debugger to help with these kinds of things rather than implementing these features within ganache.

We don't have any plans to implement this unfortunately. Thanks for the suggestion however!
