Identify openshift-logging versions installed from stable channel

[Shrivaibavi]

we dont provide any specific version of logging to be installed on the cluster, we use channel stable that pulls right versions according to OCP version. At times it gets difficult to debug the failure without the right logging version.

We will need to log the openshift-logging versions

oc adm must-gather --image=

oc get deployment cluster-logging-operator -n openshift-logging -o jsonpath={.spec.template.spec.containers[].image}
