🚀 Feature Request: quiet mode for wrangler

[MinmoTech]

Describe the solution

I accidentally reported this on the original wrangler repo first: https://github.com/cloudflare/wrangler2/issues/2615

A kind of warning/link to the wrangler2 repo might be nice there :)

My actual issue:

I want to use r2 and d1 in scripts with wrangler. Wrangler already has a nice json output (when redirecting stdout), but it also prints spammy lines before that output:

🌀 Mapping SQL input into an array of statements
🌀 Parsing 1 statements
🚣 Executed 1 command in 32.160559952259064ms
[
  {
    "results": [
      {
        "test1": "test",
        "test2": "test",
        "test3": 0,
        "test4": "test"
      }
    ],
    "success": true,
    "meta": {
      "duration": 32.160559952259064,
      "last_row_id": null,
      "changes": null,
      "served_by": "primary-fc09486d-3681-4906-a109-0b5e3d7737ab.db3",
      "internal_stats": null
    }
  }
]

The command I ran was NO_D1_WARNING=true wrangler d1 execute test_db --command='SELECT * FROM test_table

I would like a quiet mode for wrangler that suppresses the lines before the json output.

Describe the alternatives

Are there any alternatives to solving this problem? If so, what was your experience with them?

Those first few lines could be printed to stderr instead of to stdout.

Fair ask - we do have WRANGLER_LOG as detailed in https://developers.cloudflare.com/workers/wrangler/system-environment-variables/ but I don't know if it'll handle this case, i'll add it to our backlog

I have now tested WRANGLER_LOG, with level log it still includes the messages with emoji when piping, on info and lower it does not output anything when piping.

On level info when not piping it correctly outputs just the table.

So if the piping behavior would be fixed this would be a solution :+1:

Thanks already!

In my search for a --quiet CLI option for deploy, I stumbled across WRANGLER_LOG, which is helpful... but any chance there's a way to silence the 🌎 Uploading... (#/#) message? It's output even for none and error which seems odd.
