feat: add support for using Etherscan as a Query Engine [APE-636]

[fubuloubu]

What I did

Partially a realization that Etherscan already has support for several of the types of queries that are supported in our core data query model, so just enabling support for that

How I did it

Copy-pasted code from this PR: https://github.com/ApeWorX/ape/pull/1277

How to verify it

Install Etherscan plugin and it works with account.history requests

This PR was missing documentation and even though the box got checked. I am going to add it now because I forget entirely how to use this feature and I need to call the API that is now hidden behind the query manager
