Fixes #619

Summary of changes in this pull request

  • Introduces better handling of Calliope configuration (by differentiating between configuration from files, overrides and runtime).
  • Limits backend access to only things it needs (math, defaults, build config, data)
  • Better data handling to avoid duplicating information between the backend and the model object (unless necessary).
  • Removes unnecessary attributes

See this table: #619 (comment)

Reviewer checklist

  • Test(s) added to cover contribution
  • Documentation updated
  • Changelog updated
  • Coverage maintained or improved

@brynpickering first step towards the new attribute setup. This one fixes how math dictionaries are handled.
Some tests related to operate mode seem to be failing... but I thought that feature was not working???

I'll try to debug that before continuing.

I would prefer this step to be in IO, i.e. pass math to IO

@brynpickering this fix is causing some VERY weird behavior on the backend (actually reintroducing #623) and around operate mode.
I will try to re-approach with your suggestions and by first only cleaning model.py. I will only introduce the backend changes after making sure that everything on the front is behaving adequately.

operate mode is working (#539)!

In that case, shouldn't we re-activate the tests that check it / remove the unnecessary ones?

My approach was incorrect. Retrying!
