    Add default quota class into DB during migration

    For some time now use_default_quota_class has been the
    default setting for Cinder. Cinder, however, has not been putting
    any defaults for the default quota class into the database. This
    resulted in any command that queried for the default quotas to cause
    the message "Deprecated: Default quota for resource: <resource> is set
    by the default quota flag: <quota flag>, it is now deprecated. Please use
    the default quota class for default quota."

    This commit resolves this issue by setting the default value for volumes,
    snapshots and gigabytes in the quota_class table at migration time if there
    is not already a class_name of 'default' in the quota_classes table.

    Unit tests are included with this commit.
