e2e tests do not work on OpenShift

[pavolloffay]

The e2e tests does not work on openshift bc:

• jaeger-operator/test/e2e/daemonset.go

  Line 143 in 610d415

  err = WaitForIngress(t, f.KubeClient, namespace, "agent-as-daemonset-query", retryInterval, timeout)

• personally on minishift I could not select default namespace and our tests depend on services (es, cassandra) deployed in default namespce

Most of the work here is done. There are two small bugs left, #326 which is a fix to get the all-in-one-with-ingress test working on OpenShift, and #327 for the DaemonSet test, which is currently blocked by #322. I think this can be closed.
