Clone from Run UI is terrible with JSON

[martin-laurent]

What happened:
Try to clone a run (via the clone run button) that uses JSON strings as run parameters.
While the JSON run parameters show decently enough on the run's config tab (see #2713 for issues about that),
cloning such a run shows minified JSON in the form. This is a terrible user experience for someone that just wants to iterate on hyperparameters for example.

What did you expect to happen:
A similar but editable snippet of JSON to be rendered instead of the minified line of text

What steps did you take:
Cloned a run that contains JSON like run parameters

Attached is a screenshot of the config page that renders JSON snippet:

and its direct equivalent when clicking on the clone run button:

Thanks! That sounds useful.

I don't currently have time to work on this, anyone is welcome to contribute before I've got some bandwidth on this.

Providing a button nearby that can change the text box to a multiline editor might be helpful.

bumping a little priority because this is low effort and a solid use case.

Thanks @fenglixa! You are welcome, but @drewbutlerbb4 has already made a PR. Let's avoid duplicate efforts.

Yes, I found that already PR on this issue. Thanks @Bobgy @drewbutlerbb4

Removing the label, as it is obviously more complex than I thought. Thanks @drewbutlerbb4! Well thought through the use case.
