Description of problem:
Check the egressnetworkpolicy crd the 'scope' is Cluster, that means the egressnetworkpolicy is for whole cluster. it caused we cannot create same 


In openshift 3 version. it is only namespaces level. see the 3.11 docs description: "EgressNetworkPolicy describes the current egress network policy for a Namespace"



Version-Release number of selected component (if applicable):
oc v4.0.0-alpha.0+62de992-802
kubernetes v1.11.0+62de992
features: Basic-Auth GSSAPI Kerberos SPNEGO


How reproducible:
always

Steps to Reproduce:
1. Create one namespaces and create one egressnetworkpolicy
   
   oc create -f https://raw.githubusercontent.com/openshift-qe/v3-testfiles/master/networking/egress-ingress/dns-egresspolicy2.json -n test1

2. Create same one in namespaces test2
  oc create -f https://raw.githubusercontent.com/openshift-qe/v3-testfiles/master/networking/egress-ingress/dns-egresspolicy2.json -n test2

3. Check the egressnetworkpolicy crd 
  
   $ oc get crd egressnetworkpolicies.network.openshift.io -o yaml | grep scope
  scope: Cluster


Actual results:

step2. Cannot be created since step 1 had been created one already
step3. the scope is Cluster

$ oc get crd egressnetworkpolicies.network.openshift.io -o yaml
