Have you considered using OpenShift instead of Kubernetes? It comes with vastly improved multitenancy features, as well as other aspects, in regards to plain Kubernetes. OKD, the open sourced package of OpenShift allows full self-hosting: https://www.okd.io

OpenShift comes with its own headaches from my understanding. And we are too deep into Kube to switch now.
