[Lens] auto-formatting for formulas

[drewdaemon]

Describe the feature:
Large formulas can become quite unwieldy and difficult to read. It would be nice if we had an automatic formatter to keep things ✨ beautiful ✨ .

I would vote for an on-demand auto-formatter like the one in DevTools or Vega

Just some usecases for this. As we progress moving all our dashboards to Lens from other types of viz, the complexity of formulas increases.

Since formulas usually end up being a single line by default, it would be nice to indent it using some very basic rules, like @dej611 , a on-demand manual linting is just fine, if it happens to be automatic it's even better, but still optional.

A basic example could be something like newlines when using , and newline + indent for ( and )

Another option that Devtools has, is that it will slightly highlight which brackets you are in-between. When working on large formulas, it is extremely hard to find out if you are missing a closing bracket, or in which nested bracket you are currently inside.

I like this point a lot.
