Pull request #2832 (2023-08-24 14:12:19)

Fix bug with kubernetes.standby_leader_label_value
When running with the leader lock Patroni was just setting the `role` label to `master` and effectively `kubernetes.standby_leader_label_value` feature never worked.

Now it is fixed, but in order to not introduce breaking changes we just update default value of the `standby_leader_label_value` to the `master`.
