Support Argo Rollout controller object as a first class citizen

[adriananeci]

Description

Initially, we naively thought that if a pod is managed by a replicaset, then that replicaset is managed by a deployment object.
This is no longer the case, since objects like Argo Rollouts are also leveraging the replicaset objects to handle pods.

This PR adds support for Argo Rollout controller object as a first class citizen in shredder, and adjust their spec.restartAt filed setting when a rollout restart is identified as needed by k8s-shredder. See https://argo-rollouts.readthedocs.io/en/stable/features/restart/#restarting-rollout-pods for more details.
