Add labels to the Containerfiles

[piotrpdev]

Description

One of the Containerfiles we use already has some labels to describe the image:

ai-edge/pipelines/containerfiles/Containerfile.ab-jq

Lines 8 to 11 in a1fbed4

	LABEL org.opencontainers.image.licenses="MIT"
	LABEL org.opencontainers.image.title="ab-jq"
	LABEL org.opencontainers.image.source="https://github.com/opendatahub-io/ai-edge/blob/main/pipelines/containerfiles/Containerfile.ab-jq"
	LABEL org.opencontainers.image.url="https://quay.io/repository/rhoai-edge/ab-jq"

It would be nice to have these for the other ones too.

Here is the OpenContainers Annotations Spec.

A/C

• Add more labels to https://github.com/opendatahub-io/ai-edge/blob/a1fbed4008504f16e9bb9e870ee46e2789bddd0a/pipelines/containerfiles/Containerfile.ab-jq
  • It already has some but we could add more e.g. to specify the author and description of the image.
• Add labels to https://github.com/opendatahub-io/ai-edge/blob/a1fbed4008504f16e9bb9e870ee46e2789bddd0a/pipelines/containerfiles/Containerfile.openvino.mlserver.mlflow
• Add labels to https://github.com/opendatahub-io/ai-edge/blob/a1fbed4008504f16e9bb9e870ee46e2789bddd0a/pipelines/containerfiles/Containerfile.seldonio.mlserver.mlflow
• Test the Containerfiles still work properly after you make your changes (can't be too safe)

Just note that the labels should likely be automatically generated, not static, if the user uses their own Git and Quay repositories.

As for org.opencontainers.image.url, I would argue that link to the image registry is not useful. We might want to set org.opencontainers.image.title and/or org.opencontainers.image.description instead.
