Expiring Environment Variables/Context Variables

I often would like to store a short-lived API key or something into Spacelift and I often find myself updating the description to say “This expires at this date” for this context env var.

It would be nice if spacelift could understand the concept of short-lived things, have the ability to set an expiry date on an env var and then when spacelift tries to trigger a run it could fail saying “Variable expired, please update”
