Add Scipy fitting backend #1907 (Christoph)
How to implement fitting the background normalization #1804(Axel)

Add a HadronicBackground model class and treat it as a regular model component, but not applying IRFs to it. This could be handled in three ways:
- Implement the HadronicBackground as special case in ModelEvaluator and do not apply IRFs
- Define flags on models whether to apply IRFs or not
- Make IRFs part of the model specification (like "edisp(psf(exposure * sources)) + background". The latter is what sherpa does, but it is significantly more work.
Any other suggestions?
