latest README instructions for ejb-txn-remote-call quickstart:  

To uninstall the AMQ Streams operator (global installation):
----
oc delete -f charts/eap-operator-sub.yaml --wait --timeout=10m0s
oc delete csv --all -n openshift-operators
----

oc delete csv --all -n openshift-operators is problematic as openshift-operators is shared namespace, possibly already containing many more operators independent to our quickstart but the command will delete CSV for all of them and not just for the  operator we want to remove.

So the instruction is potentially dangerous for users.
