Support Drupal's configuration override system

Let see if the tests will pass. Also is there a way you can provide a sample code of how the override is done?

Simple Code for testing (placed in setting.php or settings.local.php):

$config['charts.settings']['advanced']['requirements']['cdn'] = FALSE;

More advanced options are in the documentation → .

Preconditions:
- CDN should be allowed in the advanced configurations.
- Used library should be any but Google (that one lacks the config-check).
- The library itself should not be installed for the test.

Testing:
Place the code and go to /admin/reports/status.

Results:
Without patch: CDN-warning appears.
With patch: CDN-warning does not appear.

Background:
The overrides should work for any of the configurations. The CDN-Option is relatively simple to test since it shows almost directly in the status report.

If the test pass which I think it will, this should be committed. Also @lars.stiebenz please don't change the version because that's where the commit will be applied to. Also let see if we can get another person than me and you to RTBC. Thanks for the patch.

Looks great. Thank you!
