feat(k8s): in-cluster building

Moving this from our closed-source version. This adds an option to build
container images inside Kubernetes clusters, and by extension removes the
need for Docker and Kubernetes running on developer machines.

Use it by setting `buildMode: "cluster-docker"` in the `kubernetes` provider
configuration.
