Operator is not aware of Secret/ConfigMap updates (WildFlyServerSpec#envFrom) - this could lead to inconsistencies

User is able to share environment variables in a ConfigMap or Secret and pass it to Operator via WildFlyServerSpec#envFrom field. Problem is, that Operator is not aware of changes in Secret/ConfigMap (only reference change is recognized - add or remove ConfigMap/Secret reference). This could lead to inconsistency of environment between pods in a single project (moreover this could lead also to inconsistency between projects in case that ConfigMap/Secret is shared by them).

The reaction on ConfigMap/Secret content should be doable, see https://blog.questionable.services/article/kubernetes-deployments-configmap-change/

reproduce

• create a config map with ("foo1", "bar1") entry
• create an operator (size = 1) with a reference to the config map
• update the config map - add ("foo2", "bar2") entry
• resize the operator

actual

$ oc get pods
NAME                                READY   STATUS    RESTARTS   AGE
eap-cd-0                            1/1     Running   0          112s
eap-cd-1                            1/1     Running   0          94s
wildfly-operator-55b544c4bb-wts8l   1/1     Running   0          2m1s

$ oc rsh pod/eap-cd-0
sh-4.4$ env | grep foo
foo1=bar1

$ oc rsh pod/eap-cd-1
sh-4.4$ env | grep foo
foo1=bar1
foo2=bar2

expected

$ oc get pods
NAME                                READY   STATUS    RESTARTS   AGE
eap-cd-0                            1/1     Running   0          112s
eap-cd-1                            1/1     Running   0          94s
wildfly-operator-55b544c4bb-wts8l   1/1     Running   0          2m1s

$ oc rsh pod/eap-cd-0
sh-4.4$ env | grep foo
foo1=bar1
foo2=bar2

$ oc rsh pod/eap-cd-1
sh-4.4$ env | grep foo
foo1=bar1
foo2=bar2

Environment:
operator version: 467407a
openshift version:

OpenShift version: 4.1.11
Kubernetes Master Version: v1.13.4+df9cebc

Out of curiosity, is there is way to rollout the pods manually as oc rollout was designed for DeploymentConfigs and cannot be used here?
