when I reduce the volume of the quota does not validate the snapshot

[Adriano]

Steps to test:

> Access the admin user in painel horizon
> New or edit your project > Go "Total Size of Volumes and Snapshots (GiB)" > Set to 2GB.
> To access a user of this project.
> Create Volume with 1 GB
> Create a snapshot
> Check in overview the quota "Volume Storage" if quota is exceeded
> Logout this session and login with user admin
> Change the quota in "Total Size of Volumes and Snapshots (GiB)" to 1GB
> Logout of the admin user and login with the user 1GB quota.
> Check in overview the quota "Volume Storage", if used 2GB of 1GB

Erro description:
The horizon does not consider the value busy snapshot to decrease the volume quota in GB.

    Fix volume storage usage value

    When calculating the used volume storage value to compare against
    "Total Size of Volumes and Snapshots", only the size of volumes
    was being used while volume snapshots were ignored. This allows a
    user to update the "Total Size of Volumes and Snapshots" quota to
    a value that is below what was currently being used without the
    expected error.

    This patch updates _get_tenant_volume_usages to use both volumes
    and volume snapshots. It also updates a test to reflect the correct
    "used" value.
