Glance-Cascading Patch

Introduction

*For glance cascading, we have to create the relationship bewteen one cascading-glance and some cascaded-glances. In order to achieve this goal, we using glance's multi-location feature, the relationshiop can be as a location with the special format. Besides, we modify the image status changing-rule: The image's active toggle into 'active' only if the cascaded have been synced. Because of these two reasons, a few existing source files were modified for adapting the cascading:

glance/store/http.py glance/store/init.py glance/api/v2/image.py glance/gateway.py glance/common/utils.py glance/common/config.py glance/common/exception.py
