bfc7d5dd9f feat(preview): Implement scanning for previews 
This work similarly to the move preview job to migrate the previews to
the new DB table and also reuse some code.

So when we are finding files in appdata/preview, try adding them to the
oc_previews table and delete them from the oc_filecache table.

18fbacdd8d perf(preview): Split preview data to new table 
The new oc_previews table is optimized for storing previews and should
decrease significantly the space taken by previews in the filecache
table.

This attend to reuse the IObjectStore abstraction over S3/Swift/Azure
but currently only support one single bucket configuration.
