test: ganache => hardhat

[jchappelow]

This replaces Ganache with Hardhat.

Ganache project is now dead, and the advice is to migrate to hardhat: https://consensys.io/blog/consensys-announces-the-sunset-of-truffle-and-ganache-and-new-hardhat

Several things were done to accomplish this:

• create a hardhat docker image like the one we were using for ganache: our kwildb/hardhat Dockerfile repo and pushed to Hub
• eth_maxPriorityFeePerGas is not supported by Hardhat (it's a go-ethereum invention, not in the RPC spec): transact() attempts to use unsupported eth_maxPriorityFeePerGas via JSON RPC on Kovan ethereum/go-ethereum#23479. We must set the dynamic transaction fee caps, otherwise the go-ethereum methods try to use eth_maxPriorityFeePerGas to get the "tip" cap with this non-existent RPC
• contract deploy fails if we don't give it a gas limit set because it tries fee estimation for the deployment transaction and errors with "eth_estimateGas: Contract creation without any data provided". I don't know the cause of this bug, but we can work around it.
• The compose health check waits for the log "Started HTTP and WebSocket JSON-RPC server" in the hardhat docker container.

NOTE: back to draft because there are too many hoops to jump through until hardhat is updated for it's eth_call handling. See #630 (comment)
The v2.22.5 release fixed the issues: https://github.com/NomicFoundation/hardhat/releases/tag/hardhat%402.22.5

Changing to draft since this one is proving painful to fully resolve until there is resolution to NomicFoundation/edr#360, such as NomicFoundation/hardhat#4718. In short, hardhat does not recognize input as the field for parameters in eth_call and some other RPCs although that is to-spec, which is understandable since data was the field used broadly and in go-ethereum prior to 1.13.

EDIT: They've resolved the issue in the latest release: https://github.com/NomicFoundation/hardhat/releases/tag/hardhat%402.22.5

This is finally unblocked. I think we can go ahead with dropping Ganache from our integ tests now.

Approving but I think @Yaiba should take a look since he knows more on this

[jchappelow]

We should make this change before we make the release branch. Our hardhat dockerfile is here: https://github.com/kwilteam/hardhat
