Version-Release number of selected component (if applicable):

version   4.0.0-8   True        False         6h        Cluster version is 4.0.0-8

$ ./bin/openshift-install version
./bin/openshift-install v0.8.0


How reproducible:
Always

Steps to Reproduce:
1. create "openshift-logging" namespace `oc create -f cluster-logging-operator/manifests/01-namespace.yaml`
2. create operator group object in openshift-logging
3. create subscription in openshift-logging
4. wait until cluster-logging-operator and elasticsearch-operator pod in running status, create cr in openshift-logging `oc create -f cluster-logging-operator/hack/cr.yaml`
5. check resources and pod logs in openshift-logging


Actual results:
kibana, fluentd and curator cronjob are not deployed when using olm to deploy logging EFK stack.
The cluster-logging-operator should provide default values for these Environment.

Expected results:
