This PR added the feature to ignite multi-node testnet.

Test steps:

1. ignite scaffold chain github.com/test/mychain
2. cd mychain
3. go install ./...
4. ignite testnet multi-node

The interface looks like this:

The feature is done, but the documentation hasn't been written yet. I plan to complete it tomorrow.

Hey, we've changed a bit the requirements and simplified the config.yaml: https://github.com/ignite/cli/issues/4374#issuecomment-2386058282

In short, we should use the existing validators section for multi-node. We should add a comments that says the fist validator is used in chain serve and all validators are used in testnet multi-node. For random, less not have them in the config.yaml anymore, but just let multi-node take a flag.

Here is the new display result, there will be 5 daemon lines for each node:

we should use the existing validators section for multi-node.

And I modified the use of the existing validators section for multi-node.

@likesToEatFish can you change the command so we can use the chain serve instead of the new multi-node command

I don't think it should use chain serve. The validator field makes sense but chain serve should be imho for a single validator.

I added color to the console screen @julienrbrt , it looks like this:

Thanks! Are you able to add a sort a menu/status bar to quit a node easily? So that it has a real TUI feeling

[julienrbrt]

Just as a way to tell/let the user how to kill/restart a node easily. Then I think it's good to go 👍

Sorry, I replied but for some reason it is pending

[likesToEatFish]

I apologize for the many comments I've provided that are still pending. I didn't notice their status, which serves as a lesson for me to stay more attentive in the future.
