if Pipeline is failed only briefly, don't simply reapply spec immediately

[juliev0]

Describe the bug

I've noticed that if you update the ISBService, the Pipeline will momentarily indicate that it's "Failed". I'm concerned about this potential scenario:

1. User updates both isbsvc and pipeline in github
2. ArgoCD uses sync waves such that it will update isbsvc first
3. isbsvc is updated, which pauses pipelines
4. isbsvc is done, so pipelines are allowed to run
5. pipeline is temporarily marked "Failed" because "isbsvc is unhealthy"
6. Numaplane updates the Pipeline spec without pausing because the pipeline is technically "Failed"

Therefore, we should have a delay after which if it's still failed, we can just do the reapply.
