[dockerize] add Label Schema support in pkg-dockerize and pkg-aci

[mattray]

Docker Inc. express a preference that container labels should be namespaced. Label Schema is a community project to provide a shared namespace for use by multiple tools, specifically org.label-schema.

http://label-schema.org/rc1/

Example here: https://medium.com/microscaling-systems/new-for-the-image-conscious-container-label-schema-org-78654a270f07

Metadata

LABEL org.label-schema.vendor="Microscaling Systems"
org.label-schema.url="https://microscaling.com"
org.label-schema.name="Microscaling Engine"
org.label-schema.description="Optimal resource util"
org.label-schema.version="1.2.3"
org.label-schema.vcs-url=$VCS_URL
org.label-schema.vcs-ref=$VCS_REF
org.label-schema.build-date=$BUILD_DATE
org.label-schema.docker.schema-version="1.0"

Much of this could be pre-populated from Habitat and then exposed with CLI options.

Nice, thanks for tracking--I've been meaning to catch up on this initiative.

This could be a super great feature! Thanks for opening this issue @mattray

Now that we have an updated codebase of exporting Docker images (via #3213), I'd like to add as much labelling and metadata as we possibly can. Due to time though, this can come in the near future--I want to make sure our Docker exporting is solid before adding more.
