Make example manifests minikube-friendly.

Remove fixed namespace from all manifests, reduce resource requests.
Remove the storageclass default, since it is not present in minikube.

Use the team name instead of integer id, remove unused robots.
The manifests are still compatible with the non-local deployment,
the only difference is that now a namespace is requred (assuming
that the operator can only be deployed in a specific namespace.)
