REST API for requesting kernels doesn't seem to work anymore

See original GitHub issue

Recently @ines and I discovered that requests to BinderHub’s kernel API wasn’t working anymore (neither for Juniper, nor for thebelab). An attempt to request a kernel results in a version of this error:

Failed to load https://hub.mybinder.org/user/binder-examples-requirements-69hfkvk9/api/kernels?1539279191043: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'https://minrk.github.io' is therefore not allowed access. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

I agree the z2jh import is strange
