Bug 1664941

Description of problem:
Deploy logging via OLM, got an error when creating CR using https://raw.githubusercontent.com/openshift/cluster-logging-operator/master/hack/cr.yaml :
$ oc create -f hack/cr.yaml 
The ClusterLogging "example" is invalid: []: Invalid value: map[string]interface {}{"apiVersion":"logging.openshift.io/v1alpha1", "kind":"ClusterLogging", "metadata":map[string]interface {}{"uid":"3e0b0b1b-149b-11e9-b607-069bc7021f3c", "selfLink":"", "clusterName":"", "name":"example", "namespace":"openshift-logging", "creationTimestamp":"2019-01-10T05:47:40Z", "generation":1}, "spec":map[string]interface {}{"collection":map[string]interface {}{"logs":map[string]interface {}{"fluentd":map[string]interface {}{}, "type":"fluentd"}}, "curation":map[string]interface {}{"curator":map[string]interface {}{"schedule":"30 3 * * *"}, "type":"curator"}, "logStore":map[string]interface {}{"elasticsearch":map[string]interface {}{"nodeCount":1, "redundancyPolicy":"SingleRedundancy", "storage":map[string]interface {}{}}, "type":"elasticsearch"}, "managementState":"Managed", "visualization":map[string]interface {}{"kibana":map[string]interface {}{"replicas":1}, "type":"kibana"}}}: validation failure list:
spec.logStore.elasticsearch.replicas in body is required

Then add "spec.logStore.elasticsearch.replicas: 1" in cr.yaml, and create it again, the CRs can be created, and ES pod could start, but no resources for curator, kibana and fluentd:
$ oc get pod
