[Value Stream Analytics] Group and project level show different values

Problem to solve

The Value Stream Analytics (VSA) feature exists at both the group level and the project level. At the group level you can select a specific project. The values displayed when you do that are not always the same as those displayed at the project level.

Further details

This is not a bug. The values differ because the project level is still using the original backend, whereas the group level is using the new backend that was introduced to accommodate Value Stream Analytics: Customizable Stages. The new backend is more accurate. But the new backend requires non-negligible effort to implement, so implementation was deferred.

Proposal

Value Stream Analytics at the project level should use the new query backend, but no functionality should change. Specifically, Value Stream Analytics at the project level should not have customizable stages.

What does success look like, and how can we measure that?

The Value Stream Analytics features show the same data at the group and project level for any given project.
