Add support for k8s init containers defined in docker-compose files
using the `laconic.init-container` label. Services with this label
set to "true" are built as init containers instead of regular
containers in the pod spec.
This enables stacks to fetch runtime-created ConfigMaps (e.g. from
deployer jobs) before the main containers start, without requiring
manual operator steps between deployments.
Example compose usage:
services:
fetch-config:
image: bitnami/kubectl:latest
labels:
laconic.init-container: "true"
command: ["sh", "-c", "kubectl get configmap ..."]
volumes:
- shared-config:/config
