Glance-client doesn't support image deletion by query in v2

[wangxiyuan]

As glance default api version is 2 now, when users delete image like:
    glance image-delete xxx1 xxx2
It will return an error:
    glance: error: unrecognized arguments: xxx2

While glance v1 support this function. So we should add it in V2
