create volume workflow does not compute quota usage correctly

[Doug Fish]

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."

    Use sum of volumes and snapshots for cinder usage

    The cinder quota on gigabytes is the sum of both volumes and snapshots,
    therefore in the horizon view we should be representing usage as the
    combination of volumes and snapshots, otherwise users will be confused
    when getting quota errors on volume or snapshot creation.
