kitchen: Add manifest for kitchen screen server

I decided to run the kitchen screen service in Kubernetes rather than on
the Raspberry Pi in the kitchen.  This will hopefully make it a bit more
reliable and easier to update.  It will also make it easier to rebuild
the OS on the Pi, if it ever becomes necessary, since it really only
needs Firefox (and MQTTDPMS) now.
