Move Fujitsu ETERNUS DX related file

Since there are three volume driver files relating to
Fujitsu ETERNUS DX in cinder.volume.drivers.fujitsu,
Due to the need to distinguish from the new series,
I make 'eternus_dx' directory at cinder.volume.drivers.fujitsu
and I move these files to the directory.

+upgrade:
+  - The Fujitsu DX driver names have been updated to distinguish
+    them from other Fujitsu storage. The module path
+    ``cinder.volume.drivers.fujitsu`` should now be updated to
+    ``cinder.volume.drivers.fujitsu.eternus_dx`` in ``cinder.conf``.
+    Support for the previous driver naming will continue to work,
+    but will be removed in a future release.
