Platformshconfig

Added

* `CHANGELOG` added.
* `on_dedicated` method that determines if the current environment is a Platform.sh Dedicated environment. Replaces deprecated `on_enterprise` method.

Changed

* Deprecates `on_enterprise` method - which is for now made to wrap around the added `on_dedicated` method. `on_enterprise` **will be removed** in a future release, so update your projects to use `on_dedicated` instead as soon as possible.

* `get_upstream_routes` method returns an object map that includes only those routes that point to a valid upstream.

* Removes guard on `variables()` method.

Changed

* Refactors dynamic property access to be more permissive.
