feat: preserve the folders when restoring dashboards (#4715)

* Preserve the folders when restoring dashboards

Use the dashboard UID instead of the dashboard name to get the folder
ID. This way, the dashboards get restored to their current location
instead of the root folder.

* Remove unused DS_CLOUDWATCH data source
