Pools in stretch clusters will all use the same crush rule that is generated by the operator when configuring the cluster for stretch mode, with replica 4 and two replicas per failure domain. Pools cannot create new crush rules, so we require that replica be 4 when the pools is created, EC is not allowed, and no new crush rule will be created.
