Summary:
Allow users to enable/disable iCloud syncing for each 3rd party app individually at the same place where it is possible to enable/disable it for the default apps like contacts, calendar, reminders, etc.

Steps to Reproduce:
- Open the settings app
- Choose iCloud

Expected Results:
- Each 3rd party app with iCloud entitlements should be listed
- On/Off switch for each of these 3rd party apps

Actual Results:
- No 3rd party app with iCloud entitlements is listed
- Only all 3rd party apps can be deactivated as a whole by disabling "Documents & Data"

Regression:

Notes:
Instead of having each app incorporate a setting individually, this should be handled in one place for clarity and avoiding confused users. If at a place it is possible for all standard iOS apps, it should be possible for 3rd party apps too. As already done with the location services in the global settings app.
