Subject: [PATCH] Add selector to StatefulSet definition (#2011)

This adds the `selector` to the Patroni Kubernetes StatefulSet spec

Without it, one gets errors like
```
error: error validating "patroni_k8s.yaml": error validating data: ValidationError(StatefulSet.spec): missing required field "selector" in io.k8s.api.apps.v1.StatefulSetSpec; if you choose to ignore these errors, turn validation off with --validate=false
```
(as mentioned in #1867)
