Fix conf for minikube (zalando#301)

* Bump up a Spilo version to use Patroni >= v1.4.4 ; this fixes issues with k8s 1.10 API changes

* Bump up an operator version to use the new 'etcd_host' default value

* Re-use 'zalando-postgres-operator' as a pod service account and add extra RBAC permissions to make it work

* Document in quickstart connecting to Postgres via psql
