Fix trailing leader election cm when using helm
Fix trailing leader election cm when using helm

When removing an ingress controller deployment managed by helm.
A leader election ConfigMap would be left behind because it was created 
by the ingress controller and not managed by Tiller/Helm.

This commit pre-allocates the ConfigMap so it is now managed by Helm.
