noticed the following while testing docs:

• by default, all pods get created in the same namespace as the CR. This means that oc cluster up, as it stands, will create all istio pods in the istio-operator namespace as seen here: http://pastebin.test.redhat.com/754371
• the operator is no longer creating the istio-system project and this functionality isn't in the oc cluster up command either. One of these two should take care of this responsibility so that the we can keep the process for the user as simple as possible.
