A "Plan" defines:

• which tracker is Program Increment
• which trackers (one or several) can be planned in this Program Increment

It renames the former concept of "Planning".

At Program level, there is only one Plan.

This Plan accepts:

• 1 to N local trackers as backlog eg [Features, Enablers]
• 1 tracker as Program Increment

There is a new database table specific to ScaledAgile to store this. It is not the same table as AgileDashboard.
The REST route will have a form PUT /projects/:id:/scaled_agile_plan and the body contains:

• The tracker id that is Program Increment
• The list of tracker ids that can be planned in this Program Increment

The user calling this route must be Project Admin of the Program.
