[Support Levels] Blog outlining levels and how to use our team's tool to validate them

This is related to next steps on issue #192, "Next steps on Support levels in Package.json"

The issue title is a bit of a misnomer since the team seems to have decided at the conference (with input from the larger group) that it would be better to keep the support level info to a separate file rather than adding to the package.json file.
