[feature] network policies should not have namespace in the name

[csantanapr]

currently deny all creates with the namespace name

# Source: team/templates/networkpolicy/ingress/deny-all.yaml
apiVersion: networking.k8s.io/v1
kind: NetworkPolicy
metadata:
  name: namespace2-ingress-deny-all
  namespace: namespace2

it should be like this

# Source: team/templates/networkpolicy/ingress/deny-all.yaml
apiVersion: networking.k8s.io/v1
kind: NetworkPolicy
metadata:
  name: ingress-deny-all
  namespace: namespace2

this looks like a break in backwards compatible would require a major version bump
