      Before this update, when using the new "1x.pico" size with the Loki Operator, the PodDisruptionBudget created for the ingester Pod allowed Kubernetes to evict two of the three ingester Pods. With this update, the Operator now creates a PodDisruptionBudget that only allows eviction of a single ingester Pod.

      Description of problem:

      The 1x.pico size of LokiStack configures three ingesters by default with a replication factor of two. This means that one of the ingesters can fail without the log ingestion being interrupted.

      The PDB generated by the Loki Operator allows two ingesters to fail, which only leaves a single ingester alive, which is not enough for the configured replication factor.

      Version-Release number of selected component (if applicable):

      Loki Operator 6.1.z
