glance-manage does not read configuration correctly

Hi guys,

I have been utilising the glance Folsom packages provided in the Ubuntu Cloud Archive repo. On installation of a new glance server using a glance-api.conf and glance-registry.conf which point to mysql rather than the default sqlite backend, I am coming up across the following issue:

When running glance-manage db-sync the program doesn't seem to import the sql_connection line from either glance-api.conf or glance-registry.conf and simply does the db-sync against the /var/lib/glance/glance.sqlite file. This means the DB schema and db-sync itself are not created and performed on the mysql db!

This isn't a misconfiguration issue or connection problem, as if I modify the api.py code to set autocreate tables = True, then when starting glance-api it correctly reads the configuration, connects to mysql (not sqlite!) and creates the DB schema and performs a db-sync.

Please rectify, and push the fix to Ubuntu Cloud Archive ASAP.
