DataExtension aggregates rework #4882

I would like to be able to..

Split from #2544

Automatically calculate defined aggregates about player NumberProvider, DoubleProvider and any GraphProvider data

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

Prep work for this is underway, API additions allow developers to define which aggregates they want Plan to compute.

Graph API adds Aggregates enum which allows defining which aggregation types specific data supports. This way users get less noise in terms of useless data.

This ticket includes:

• Storing NumberProvider and DoubleProvider aggregate types in database
• Rewriting aggregate queries for NumberProvider and DoubleProvider to use given aggregate types
• Writing new aggregate queries for GraphProvider aggregates (+ aggregate graph query).
• Redesigning Boolean aggregates to include information about missing values (Yes / No / Unknown)
