Bug in the return of command 'volume qos create'

[jiahui.qiang]

When i use "volume qos create" command to create a qos for volume. I find a useless show in the item of specs:
➜ python-openstackclient git:(func-volume-qos) #openstack volume qos create hello
+----------+--------------------------------------+
| Field | Value |
+----------+--------------------------------------+
| consumer | both |
| id | 39a23ac7-b5e3-4a0a-8f03-38aa3cb4b1e8 |
| name | hello |
| specs | {} |
+----------+--------------------------------------+
➜ python-openstackclient git:(func-volume-qos) #openstack volume qos create hello1 --consumer front-end --property a=b
+----------+--------------------------------------+
| Field | Value |
+----------+--------------------------------------+
| consumer | front-end |
| id | 6190c068-d129-4dc8-b408-54760b6715d1 |
| name | hello1 |
| specs | {u'a': u'b'} |
+----------+--------------------------------------+
As is showed above,it will show useless { } in specs, when i set '--property' option.

    Fix properties format for volume qos in volume v1

    Notice that patch [1] fixed the error of properties
    format for volume qos in volume v2, but there is the
    same bug in volume v1, and the patch missed that, so
    fix the problem in v1 as well
