* Add cluster_labels and annotations to logical backup CronJob and Jobs
When using the logical backup feature, the CronJob and its created Jobs
were missing the cluster_labels and annotations that are applied to
other cluster resources. This made it difficult to filter or identify
backup jobs using the same labels as other cluster components.
Changes:
- Added ObjectMeta with labels and annotations to JobTemplateSpec
- Updated CronJob ObjectMeta to use the merged labels (including
'application: spilo-logical-backup')
- Updated tests to expect the new labels
