Optimize: n + 1 problem in facility upsert

[afzalIbnSH]

Code:

        for ca in capacities:
            facility.facilitycapacity_set.update_or_create(
                room_type=ca['room_type'],
                defaults=ca
            )

I'll do this.

The max it does is against 5 rows. So I don’t think you should be spending time here. 

Closing this.
