OpenStack Image Registry and Delivery Service (Glance)

Implement Registry Database Driver

Registered by Brian Waldon on 2012-11-15

This change is part of the kill-registry blueprint and is intended to implement a new db driver for the registry service in order to support legacy deployments based on 2 separate services.

Adding a testing plan for folks willing to give this feature a try:

* Install Glance
* Configure as usual but:
    * glance-api:
        - Make sure Glance's API v2 is enabled in both glance-api.cof and glance-api-paste.ini
        - Make sure glance-api.conf uses: data_api = glance.db.registry.api

    * glance-registry:
        - Make sure Glance's Registry API v2 is enabled in glance-registry-paste.ini:
               paste.app_factory = glance.registry.api.v2:API.factory
        - Make sure glance-registry.conf uses: data_api = glance.db.sqlalchemy.api

* Use glanceclient normally but make sure it points to the api version 2
    - glance --os-image-api-version 2 image-list
