Add "Global Auth" option to external storage

This adds the "Global Auth" option to the external storage implementation, it is basically done by reverting c2c6caee93c491de9fa9a2e7c2eea036f4974e61 from https://github.com/owncloud/core/pull/22468.

This was taken from owncloud/core which is AGPL licensed. Commited with "icewind@owncloud.com" to keep the license header signature in sync.
