metric - introduce new kube_endpoint_ports metric:
* export all relevant port infomation (port name, port number and port protocol) from an endpoint
tests - make endpoint tests endpoint.spec aware:
* endpoint port struct with multiple ports need port names per port
* single port struct doesn't need a port name
* port protocol is per default TCP
