Hardhat Plugin :: Implement impersonated signer

[Valazan]

Currently, the Hardhat impersonated signer, it's not implemented in our hardhat plugin.

Hardhat Network allows you to impersonate any address. This lets us send transactions from that account even if we don't have access to its private key.

An analysis must be done to understand how to implement this feature.
