Resync action via Seafile client command line interface seaf-cli

Please add resync action for library to seaf-cli Seafile client command line interface. Also will be good to have optionally set sync interval for library.

Here is issue about this: https://github.com/haiwen/seafile/issues/1791 with many comments, so that feature needed for many people! Any chances this feature will be implemented in next version?
