3par drivers can't delete a volume being copied

[Walt Boring]

When running the driver certification tests for Icehouse, we found a bug with the 3PAR FC/iSCSI drivers.
The tempest test calls cinder to create a clone of a volume, and then immediately calls delete on the clone. The 3PAR won't allow you to do that unless you stop the copy first. You get a very generic exception, that isn't helpful.

    Update 3PAR drivers to pass cert test

    This patch updates both the HP 3PAR Fibre Channel
    and HP 3PAR iSCSI block storage drivers so that they
    can pass the driver certification tests. We also updated
    the unit tests to use mock instead of mox.

    These versions of the drivers require the new 3.0.0 hp3parclient,
    which can be downloaded from the pypi repository:
    https://pypi.python.org/pypi/hp3parclient
    The new hp3parclient requires the 3.1.3 firmware on the HP 3PAR.

    The driver certification results:
