[PATCH] Create setup and teardown functs for dmraid devs.

[Joel Granados Moreno <jgranado redhat com>]

* storage/devices.py (DMRaidArrayDevice): Erase the activate and
  deactivate functions for the DMRaidArrayDevice.  They are no really
  being used.
* storage/devices.py (DMRaidArrayDevice): Create setup and teardown
  functions for the class.
* storage/devices.py (Device): Add the pyblock attribute to the shallow
  copy list.
