can't use mirrord over kubectl proxy

[aviramha]

Some of our users want to use mirrord over kubectl proxy which runs on a bastion host they SSH and port-forward to.
A simple way to reproduce/try it out is by running:
kubectl proxy
then in another terminal:

kubectl config set-cluster testt --server=http://localhost:8001 --insecure-skip-tls-verify=true
kubectl config set-context testt --cluster=testt
kubectl config use-context testt

then kubectl get pods works while mirrord ls fails.
mirrord ls fails because of empty user. I tried working around it by adding a "dummy" user, but that only fails in a different way (where kubectl doesn't)
