It should be possible to line break CEL validation expressions

[alvaroaleman]

We have CEL expressions that are more than 700 characters long and completely unreadable due to the fact that they have to be defined as one single long line. We should find a way to allow defining them over multiple lines.

Sounds good. I guess programming in markers has its limits :) (at least today)

Is it possible to share one of the long expressions?

We have had issues in the past where folks have tried to write supremely long expressions, but always managed to break the expressions down into smaller chunks and create a set of rules, rather than one rule to rule them all. I'd be tempted to say that you can probably achieve something similar but, without seeing an expression it's hard to say
