This commit adds resources for deploying the Home Assistant ecosystem
inside Kubernetes. Home Assistant itself, as well as Mosquitto, are
just normal Pods, managed by StatefulSets, that can run anywhere.
ZWaveJS2MQTT and Zigbee2MQTT, on the other hand, have to run on a
special node (a Raspberry Pi), where the respective controllers are
attached.
The Home Assistant UI is exposed externally via an Ingress resource.
The MQTT broker is also exposed externally, using the TCP proxy feature
of *ingress-nginx*. Additionally, the Zigbee2MQTT and ZWaveJS2MQTT
control panels are exposed via Ingress resources, but these are
protected by Authelia.
