 Description   

A new feature that's in mysql 5.7, which is very useful. Especially when we have Galera Cluster enabled, as Galera will copy all files included the undo log tablespaces to a new node. If we can do this house keeping job for the server, we can utilize disk space in a much better way, and have a new node setup much faster.

leomkkwan, I believe that this should work starting with MariaDB Server 10.2.2 (which merged the InnoDB from MySQL 5.7.9). Can you please confirm this?
