Open Stack

Hi,
We are in the process of adding the OSLO DB support to Quantum. There 
are a number of issues here:
1. The common DB code does not support foreign key constraints with 
sqlite (https://review.openstack.org/#/c/27320/)
2. The common code does not have a database cleanup. This is something 
that we use in the quantum automatic tests to try and keep the memory 
footprint small (https://review.openstack.org/#/c/27322/)
3. In the current Quantum versions all of the database configuration 
information is under a section [DATABASE]. The common code moves this to 
[DEFAULT]. If possible it would be great if we could preserve the 
current configuration file settings. This will enable us to have 
smoother version upgrades. If this is not possible then we will need a 
migration script to update configuration files. Does anyone have 
thoughts on this? I would like to make changes to the common code to 
ensure that we can use the DATABASE section.
Thanks
Gary
