Dockerfile: add LABELs

[macmacal]

Description

• Adds 2 LABELs for container images, to provide minimal build information metadata:

  • aegis.ros.distro (currently humble)
  • aegis.ros.tag

• Adds example how to build, push and pull the container image to the container registry.

Already existing images LABELs can be check with this command:

export REGISTRY_HOSTNAME=localhost
export AEGIS_CONTAINER_VERSION=latest
podman image inspect --format='{{json .Config.Labels}}' ${REGISTRY_HOSTNAME}/ceai/aegis:${AEGIS_CONTAINER_VERSION}

• Code has been (auto)formatted.
• Documentation (e.g., README, CHANGELOG, Wiki) has been updated.
