Support backoff limit for preemption due to in-cohort reclamation

[eric-higgins-ai]

What would you like to be added:
We can configure a backoff limit for pods evicted due to a PodsReadyTimeout, but would like the ability to also configure a backoff limit for other types of eviction.

Why is this needed:
We have users submitting ML training jobs to Kueue, which they then track. The default preemption behavior (retry indefinitely) will be somewhat confusing for these users to track/understand, so we would like the ability to deactivate jobs on preemption.

Completion requirements:

• Design doc
• API change
• Docs update

The artifacts should be linked in subsequent comments.
