Backlog

- Scheduled for December 2021:
    - update local kind & kubectl
    - Build controller with Kubebuilder v3.2.0
    - Remove warning for CronJob which was updated from beta to stable since Kubernetes 1.21

- add a test in spec_readinessProbe_test and spec_livenessProbe_test so that
  we test the default behaviour when no option is set from the YAML

- Scheduled for either December 2021 or Jan 2022:
    - #20 : Delete PVC

- Scheduled for May 2022:
    - #12 : Reuse PVC (see below) and Primary becomes a Replica

    As part of the available options for the field "failover.pvc", there would be:
        - "retain": the default option currently with Kubegres where PVC are kept but not reused for safety and investigation reasons
        - "delete": the PVC will be deleted
        - "reuse": if the state of the PVC is healthy, it will be reused by the newly created Replica pod. I think that matches with your suggestion?
