[Feature Request]: Structured logging via JSON

[robertkiel]

Implementation ideas

To ease (automatic) monitoring of Celestia nodes, it would be great to have structured log outputs, for rereference see Reth config that allows multiple log frontends, including JSON.

Instead of logging

infosampled header { type: 'recent', height: 23, ... }

why not log

{
    "kind": "info"
    {
        "description": "sampled header",
        "inner": {
            "type": "recent",
            "height": 23
        }
    }
}

Can I work on this?

Hey @robertkiel, this is already possible but has yet to be documented: GOLOG_LOG_FMT=json
Please try and tell if it works for you

I see that it's an external feature request. Thank you.
