When running Thanos in a distributed system, sometimes multiple receive-ingestors are lost at once. With the current StatefulSet configuration (Parallel), these are only allowed to come back one at a time, which slows recovery speed significantly. By permitting users to override the StatefulSet podManagementPolicy, they will be able to configure how Kubernetes handles updates and recovery, speeding up recovery time.
