The MGM server should check the config file to make sure that all DB nodes are configured to use it's own filesystem.

How to repeat:
Configure the system with two DB nodes running on the same machine and the same files system path

Suggested fix:
Check that FileSystemPath of DB node(s) are different from all other DB nodes. If they are equal, check that they are not run on the same machine.

I implemented that each node uses
FilesystemPath/ndb_%u_fs/ as filesystem.

This removes the need for unique filesystem paths
