Title:
  create volume workflow does not compute quota usage correctly

Status in OpenStack Dashboard (Horizon):
  Fix Released

Bug description:
  The cinder quota on gigabytes is the sum of both volumes and
  snapshots. This is not correctly reflected in the create volume
  dialog, which allows the user to attempt to create volumes when there
  is not enough quota available, which results in a useless error
  message.

  To recreate the problem:
  1) on Project->Compute->Volumes create a 1G empty volume
  2) on the same panel create a snapshot of the new volume
  3) on Identity->Projects->[your project] choose Modify Quota and set the quota for "Total Size of Volumes and Snapshots (GB) " to 3G.
  4) Note that the quota usage (2 of 3) is correctly reflected on Project->Compute-Overview
  5) on Project->Compute->Volumes click Create Volume
  *Note the the quota is not accurately reflected
  6) Attempt to create a new volume of size 2G.
  *Note the obscure failure message "Error: Unable to create volume."
