discovery(k8s): add metadata labels to endpointslices

Browse source 
This commit adds 2 new metadata labels for the endpointslice role:
* `__meta_kubernetes_endpointslice_endpoint_node_name`
* `__meta_kubernetes_endpointslice_endpoint_zone`

The latter is only present when the `discovery.k8s.io/v1` API group is
available.

I also updated the configuration doc and added an entry for the
`__meta_kubernetes_endpointslice_endpoint_hostname` label which was
missing.
