    Adding informative message when deleting a used volume type
    
    Currently when you try to delete a volume type (which is in use) Horizon
    returns a generic message.
    
    This patch includes in this message the text from the exception, resulting on
    the following message:
    'Error: Volume type '<vol_type>' is still in use.'

Title:
  Cinder volume type delete return none informative error

Status in OpenStack Dashboard (Horizon):
  Fix Released

Bug description:
  Description of problem: 
  Currently when you try to delete a volume type (which is in use) Horizon returns -> Error: Unable to delete volume type: ssd

  Notice on cinder api.log we get a better explanation->  "deletion
  failed, VolumeType in use.

  Improving Horizon's none informative error would be helpful.

  Version-Release number of selected component (if applicable):
  RHEL7
  openstack-dashboard-2014.1-7.el7ost.noarch

  How reproducible:
  Every time

  Steps to Reproduce:
  1. Create volume type
  2. Create a new volume, from volume type created above.
  3. On admin page, try to delete volume type (it should fail) but notice error message. 
  4. grep -ir error /var/log/cinder/api.log  -> will show cinder's better error notice.

  
  Actual results:
  Horizon returns -> Error: Unable to delete volume type: ssd
  None informative error.

  Expected results:
  Should return -> Error: Unable to delete volume type while it's still in use, volume type: ssd.
