When transforming the deployment status to the revision we want to bubble up the more severe condition to Ready. Since Replica failures will include a more actionable error message this condition is preferred
This isn't accurate when the Revision has failed to rollout an update to it's deployment
1. PA Reachability now depends on the status of the Deployment If we have available replicas we don't mark the revision as unreachable. This allows ongoing requests to be handled 2. Always propagate the K8s Deployment Status to the Revision. We don't need to gate this depending on whether the Revision required activation. Since the only two conditions we propagate from the Deployment is Progressing and ReplicaSetFailure=False 3. Mark Revision as Deploying if the PA's service name isn't set
