Disable colored log messages in node

[gligneul]

📚 Context

By default, some node services print log messages with color, which is problematic because some log aggregators do not parse the color information properly.

✔️ Solution

Disable log colors in all services by default. Then, add a command line option (and env var) that enables the color.

📈 Subtasks

Apply the modifications to all services:

• [ ] state server
• [ ] dispatcher
• [ ] advance runner
• [ ] inspect server
• [ ] graphql server
• [ ] host runner

Is it configurable? color is nice for local execution (with sunodo)

[gligneul]

It probably can be configurable.

I think this could be tackled with other minor format issues. Keeping all modifications in a single issue to improve code reuse will be better. https://github.com/cartesi/rollups-node/issues/25
