Note, I borrowed a bit of code from Duopixel's excellent code sample here.

Upgraded to D3v5.

"""Maps a request to a tenant using the first part of the hostname.

For example:
  foo.example.com:8000 -> foo
  bar.baz.example.com -> bar

This is a simple example; you should probably verify tenant names
are valid against a whitelist before returning them, since the returned
tenant name will be issued in a `SET search_path TO` SQL query.
