ClusterRole artillery-operator-manager-role requires `get` `list` `watch` on `configmaps` across the cluster

[justinfiore]

When I tried to run the hack/examples/basic-test-cr Load Test, it could not execute because the operator couldn't read configmaps.

I added: configmaps with get, list, watch to the artillery-operator-manager-role ClusterRole and it was able to proceed. I don't know if all 3 of those permissions are needed or only a subset.
