Allow fast-tracked rollbacks for kubectl argo rollouts undo

[sys-ops]

Summary

As of now there is no way to perform a fast-tracked rollback (skip analysis, pauses and steps entirely) if a rollout deployment has been performed successfully.

Use Cases

When would you use this?

I need that feature during incidents on production when I need to rollback to the previous stable version as fast as possible.
