Implement new task management system

[wkmor1]

Trello started being paid only for teams greater than 10 and then we moved to Microsoft Planner. We were not happy with the feature set of Planner. Pivotal Tracker was then discontinued.

Task management is now being moved to GitHub. Primarily in two "Projects" : "Epics" replacing Trello/Planner and "Tasks" replacing Pivotal respectively.

TODO:

• [ ] Add issue templates to repositories
• [ ] Add GitHub actions to repositories to automate moving tasks and epics to the appropriate projects
• [ ] Document the life-cycle of the "Epics"
• [ ] Document the lifecycle of the "Tasks"
• [ ] Create a checklist for creating a "Task"
• [ ] Automate syncing labels across repositories
