Integrated Fujitsu ETERNUS DX (fate#317486)

In order to get Fujitsu ETERNUS DX volume types working a have
integrated the configuration for it to reflect the patch included into
our SUSE packages.

This fixes the request https://fate.suse.com/317486

**I have created it on our custom branch because currently it doesn't make sense to push this upstream as the ETERNUS DX openstack files are not included upstream but within our packages.**
Change it also for emc? It's simply copied over.
