Geo: Revert alternate_url

The concept of alternate_url is fundamentally flawed, so
we are removing it before it is released.

-## Multiple secondaries behind a load balancer
-
-Secondaries are authenticated via OAuth with the primary. For security, the
-primary does not allow redirecting back to an arbitrary URL. If you want to
-allow users to log in to secondaries at a common name/load balancer URL, then
-this URL must be specified as the "Alternate URL" on every secondary behind it.

-Additionally, the load balancer should use sticky sessions, since users must
-authenticate each first request to each secondary.
