[2.0] Background strain needs to be tethered to species

[saskiad]

Is your feature request related to a problem? Please describe.
Strains are species specific. Our current enum of strains are unique to mouse.

Describe the solution you'd like
I'm not entirely sure the correct way to implement this. We currently have a short enum of 2 mouse strains. We either need to be able to point this to different enums for different species, or have a single list but know which ones are for which species and have a validation step to make sure species and strain match?

And we should probably move the list(s) of strains to the models repo?

[dbirman]

One option would be to replace species in the models repo with strain, so the species stays attached to the strain. In subject.py if someone provides a strain we can auto-populate species (or at least validate that it matches) and if someone skips the strain we still require the species.

[saskiad]

I think something along these lines makes sense.
