Document how to install the DWO on minikube/kind/ocp

[l0rd]

Description

We should document how to deploy DWO on Minikube, Kind, and OpenShift, with and without OLM, and without requiring make or go or any dev tools (kubectl, oc, curl, etc. are fine).

DWO on Kind may not work currently because admission webhooks are not supported there. If that's the case, we should discuss whether we can make admission webhooks optional (or explore other options for deploying DWO on Kind).
