argo-workflows: Workflow controller v3 fails to start on OpenShift 3.11

Summary

When tying to upgrade to Argo workflows 3, startup of the workflow controller on OpenShift 3.11 failes, because the underlying api for leader election is not available.

A configuration for disabling leader election might mitigate the situation.

Diagnostics

What Kubernetes provider are you using?

OpenShift 3.11 which is running on Kubernetes 1.11

What version of Argo Workflows are you running?

v3.0.1

The issue can be reproduced by running the default namespace install manifest

I also encountered the same issue as @vbarbaresi in Openshift 3.11 (Argo v3.0.2).
