[hardhat-verify] Verify proxy

[fvictorio]

Etherscan has a new API feature for verifying proxies instead of contracts. I don't know if this is something enough people would want to merit working on it, though. On the other hand, while this can be done manually, it wouldn't be too hard for us to add it, at least as a subtask that can be called programmatically.

Related issue with workaround: #1166

We just released a new version with support for this.

@alcuadrado this issue is about verifying proxies, not about using proxies for verifying :sweat_smile:

Looks like the mentioned fix indeed doesn't address this issue as intended

This should be the api endpoint to verify as proxy: https://docs.etherscan.io/api-endpoints/contracts#verify-proxy-contract

Maybe triggered with a simple flag --proxy ?
