Add 2020 rent stab unit counts to the Tenant Platform (#2201)

This PR swaps in 2020 rent stabilized unit counts to three queries within the tenant platform that make use of rs units:

the "DDO" sql query that generates building-level statistics for Data Driven Onboardin
the sql query that gets triggered in the rent history tool to detect a history of any rs units going back to 2007
the sql query that gets called in the housingtype API call
