Remove dependency of provider plugin from wrapper

[cbrzn]

Currently, the ethers wrap is very dependent of the ProviderModule dependency. This is because whenever we do a JSON RPC request, we do it using the dependency (ProviderModule::request).

In order to fix this, we can do the JSON RPC requests using the HTTP Plugin, and when it comes to interactions with keys (signing transaction, for example), then use the ethereum-wallet plugin to interact with these signing functions.

This would allow the wrapper to be used without any ethereum provider, just an HTTP Plugin and be able to read from blockchain easily. Making it (the wrapper) easier to interact with
