As an API user I want to be able to list all facilities in Kano by zone, LGA or Ward so that I can see all the facilities in a given area.

/fm/ward/?facility_area__area_id=1
/fm/zone/?facility_area__area_id=2
/fm/lga/?facility_area__area_id=3

/fm/ward/?facility_area__area_name=Test1
/fm/zone/?facility_area__area_name=Test2
/fm/lga/?facility_area__area_name=Test3
