Evaluate use of Milestones for enhancement boards

[eporter23]

• Configure milestone(s) for repo
• Determine if GH Milestones could be utilized for maintenance sprints, etc.
• Make sure submitters can't assign milestones?

You can go to ZenHub and view a connected GH milestone, but it seems to retrieve all of the enhancement issues whether or not they are tagged for that milestone. https://app.zenhub.com/workspaces/dlp-launch-5e73e2e1a623a3f3d2e56f15/board?milestones=Maintenance%20FY22%232022-08-31&repos=464974182. Also, the Milestone tag does not display if you view an issue in ZenHub.

Initial assessment: milestones aren't useful within ZenHub, but could be useful in the enhancement board.
