isoping: build with Docker
This will let us deploy a minimal image with isoping to GKE. After
some research I've been able to get the container size down to 6 MiB.
I've pushed this to a manually configured GKE cluster and confirmed
that it works, too.
Also include Kubernetes configs for a small cluster running on GKE.
