Allow FDW configuration to execute against non managed PostgreSQL
There is a big if geo_postgresql['enable']
guarding the recipe, regarding FDW configuration, table refreshing etc.
It's possible for the user to use an external database instead of the managed one, and configuring FDW manually is a complicated step.
We have all the required information, so we should allow under a specific flag for that configuration to run against non-managed instances as well.
