Don't wrongly identify endpoint addresses only due to equal IP
Don't wrongly identify endpoint addresses only due to equal IP

Before this patch the endpoint IP was used to identify endpoint addresses. This
leads to wrong unification of endpoints of different pods having the same IP (e.g.
non container IP in case of Mesos). This patch takes the EndpointAddress.targetRef.UID
into consideration as well.
