Geo: Support a custom database login for PostgreSQL FDW to work with pgbouncer
We found that in https://gitlab.com/gitlab-org/gitlab-ee/issues/4522#note_59422169, sharing the same user login between the FDW connection and the regular Rails DB connection would cause all sorts of errors with schema paths. To avoid this problem, provide a way to customize the username/password used by the FDW connection.
Closes gitlab-org/gitlab-ee#4522
