Add label to qualify production grade of image #33

Many products we want to put into images - as well as images as an entity themselves usually go through a pre-production lifecycle from experimental over beta, tech-preview, to production ready. Some are development-only or community editions vs fully supported. It would be helpful to have the ability to describe this in metadata.

Semantic versions are very often used to relate this information. What is an example use case where a version number doesn't provide this info.

semver shows the quality of a release, but not the context of it. there seems to be no common understanding that 0.4.0 to 0.8.0 is tech-preview and 1.0.0 upwards is always production ready. so labeling an images as 'experimental' would give some better hint than a plain (close to meaningless) 0.99.7A

Even more: most images created by Red Hat will follow the version of the primary component inside the image (e.g. a rhel7/php image would reflect the current version of php in RHEL). That does not properly indicate the production quality of the image as such.

What label would you want?

Docker uses 'environment' in their examples I think.
