Subject: [PATCH] Add HNC postsubmits and periodics

Run HNC's end-to-end tests in a Kind cluster, using a custom-built image
defined in
https://github.com/kubernetes-sigs/multi-tenancy/tree/master/incubator/hnc/hack/prow-e2e.

Note that I've set the periodics to run every 12h; this is temporary
until we've seen a few passing runs. After that point, I'll reduce the
frequency to 48h (i.e. every two days).

Tested: on my local workstation, the custom-built image successfully
runs the latest e2e tests on Kind following the instructions in the HNC
repo (see README at the link above). I have no way to test that the Prow
configs are correct as we've cobbled them together from other tests'
examples.
