3PAR: Delete a clone volume in progress needs clearer message

[Ramy Asselin]

When running tempest.api.volume.test_volumes_get.VolumesGetTest.test_volume_create_get_update_delete_as_clone
the delete (cloned) volume occurs before the volume is actually available to delete.

The error message in cinder log is:
2014-07-28 22:56:27.910 18274 ERROR cinder.volume.drivers.san.hp.hp_3par_common [req-bfd35514-8494-40d6-bc81-019061bfab3c b8a4f1d7ab1740cbb44ea4d1173c79b6 ca4738ac14184c1e8178f3d647c22940 - - -] Conflict (HTTP 409) 151 - invalid operation: Volume tuning is in progress

These error message should be made more clear that the volume is in-use and the operation should be retried later.

    Change 3PAR delete message when volume is busy

    This patch traps for when a volume is busy at
    delete time. It then logs a more useful message
    and raises a VolumeIsBusy exception.
