> Currently we don't delete the local storage when closing {{MiniOzoneCluster}}, which
will cause creating volume with the same name to fail, even in a new JVM process. Let's delete
the local storage files: {{/tmp/ozone/metadata.db}} and {{/tmp/ozone/user.db}} when closing.
> Please note this is not a complete solution. As the {{OzoneMetadataManager}}  currently
is a singleton, we are not able to create two independent MiniOzoneCluster in a single JVM.
Data maybe shared unexpectedly. Let's address that in another JIRA, if needed.
