Content Sync across environments

Hi, darcy-jean!

I was really curious about this patch, tried to install it on 3.0.x-dev, but the patch is rejected.

For example, in content_sync.install it tries to remove:
- use Drupal\Core\Database\Database;

but the original content_sync.install is missing this statement.

Is this patch already included in 3.0.0-beta1 version. Please confirm. Also, I don't see option to configure the environment setting, Deploy Setting after applying the patch. Is there anything needs to be done. Can this be tested in local environment. Appreciate help here.
