Option to create custom node startup

[SebastienGllmt]

Feedback

For my project, I want to have a custom way to create a Hardhat node that is instrumented with my own logic instead of the Hardhat one (specifically, we want opentelemetry support)

What worked in Hardhat v2

In hardhat v2, this was possible with either:

• TASK_NODE_CREATE_SERVER (as mentioned here
• By simply doing import { JsonRpcServer } from "hardhat/internal/hardhat-network/jsonrpc/server.js";

Why it doesn't work in Hardhat v3

In Hardhat v3, this is not possible:

1. There is not only a monlithic node which not only does too much for my use-case, it also has no return type
2. Doing import { JsonRpcServer } from "hardhat/internal/builtin-plugins/node/json-rpc/server.ts"; doesn't work because the path is not publicly exported

I can copy-paste the contents as-is, but that's not ideal since this folder also depends on builtin-plugins/network-manager as well

Hey @SebastienGllmt thanks for opening the issue. Can I try and understand the use case more clearly.
The goal is to get opentelemetry integrated with all requests going through the Hardhat node connecting to a remote network? And it looks as if there aren't appropriate extension points or the equivalent of HH2 where you could create a server and wrap with opentelemetry support?
