Write queries to create demographic rollup tables by FMA

[sky-t]

Per discussion with @BrianHGrant, I'll put all demographic rollup data into a single table that can be hit by the API. @futurechris will also add the response time rollups to this table.

@BrianHGrant @futurechris , I created a new table named fma_api_rollup in the db and have started populating it with demographic data by FMA. I have median response time by FMA and will add that as well.

fma_api_rollup table is now populated with the following demographic data: total population, % owner occ, % renter occ, median hh income, % with health ins, % w/o health ins, % college grad or higher, % rec food snaps, % nonwhite, % below pov line, % hh w/ member 65+, % in diff area last year
