Description of problem:
I updated the "instance" custom resource which defines my cluster-logging setup. However, the elasticsearch deployments don't seem to get updated with the new configs. Additionally, if you delete one of those deployments (I was hoping it would be recreated with the correct config), the deployment doesn't get recreated.

Version-Release number of selected component (if applicable):
4.1

How reproducible:
Happened once, haven't verified if it's easily reproducible

Steps to Reproduce:
1. Edit "instance" in the web console

Actual results:
$ oc get pod
