test: Add HostPort conformance to upstream-k8s
test: Add HostPort conformance to upstream-k8s

Now that we enable portmap chaining by default in the upstream-k8s
conformance testing script, we can enable the hostport tests.

In future we can also support this test with kube-proxy-replacement but
that requires solving a couple of additional bugs first, see issue 14287.
