Define version management of K8S API versions and schema versions

[davidfestal]

Is your feature request related to a problem? Please describe.

We should define:

• how we manage K8S API versions and JSON schema versions. How they are related together.
• how we update them,
• how that relates to release eng..., GH tagging (for GO module / package imports)

Designs on the K8s API versions and JSON schema versions can be found in https://docs.google.com/presentation/d/1ohM1HzPB59a3ajvB7rVWJkKONLBAuT0mb5P20_A6vLs/edit#slide=id.g9cf6e5096d_0_8

Proposal up for review at #278

I've also created an example make-release.sh script and GitHub actions to perform a release on my repository:

• https://github.com/johnmcollier/api/blob/master/.github/workflows/release-schema.yaml
