[danielolsen]

Pull Request doc

Purpose

Consolidate column names/types in one place, to reduce duplicate information and potential headaches when making changes.

What the code is doing

No code. Only constants being moved around.

Testing

All tests still pass.

Time estimate

5 minutes.

In this case, we don't need column_name_provider or column_type_provider any more in scenario_grid.py, do we?

There are still some uses of these that would need to be refactored:

PowerSimData/powersimdata/input/scenario_grid.py

Line 169 in b6f15a7

col_name = column_name_provider()[name]

Make sense.
