Subject: New tool to collate all information to form a good error report for
 NDB.

It will copy from each node the logs and trace dumps (if any) and create
a tarball. Having this tarball attached to a bug report greatly helps
troubleshooting and avoids user error.

It will (optionally) also get the filesystem.
