add domainsdb.info API into Business

As discussed in PR #407, Stormpath closed and joined with Okta. However, there is no indication of a free tier for Okta now. The closest thing I could find on their pricing page was joining 1 service to an Okta SSO for free, but that isn't any form of an API that we cover in this project.

Added; Battuta: A (country/region/city) in-cascade location API

we support more than just JSON endpoints here
