Eksctl: Offer `utils describe-stacks` output in pure JSON

[whereisaaron]

Why do you want this feature?
I'd like to be able to use describe stacks output to check or extract the state of eksctl cluster.
Right now the output is a hybrid/mix of plain text logging and JSON and so can't be parsed as JSON without pre-processing. And if you have to do that you might as well use the aws cli directly instead. So right now, for me, the utils comment is not very useful. But if it did output JSON, it would be quite useful (to me). JSON output would also enable JSON diff to track changes to a cluster.

What feature/behavior/change do you want?
I would like this to work:
eksctl utils describe-stacks --name=mycluster | jq <expression>
or this:
eksctl utils describe-stacks --name=mycluster --output json | jq

I can work around this by describing the stacks with the aws cli so this is just a wish list item. Just to say I think this utility would be more useful with a pure JSON output option.

Same here. This feature is really helpful for me.
