Add DB2 10.5 Support

Registered by Matt Riedemann on 2013-10-29

Add the code to sqlalchemy-migrate to support the ibm_db_sa engine to talk to DB2.

The minimum version of DB2 supported would be 10.5 for handling unique constraints with nullable columns.

Support running unit tests against DB2 10.5 Express-C on x86_64.

Depends on getting ibm_db_sa into openstack-requirements: https://review.openstack.org/#/c/48745/

Note that there are some existing DB2 blueprints for other projects but they will depend on this one (except Keystone):

Chef: https://blueprints.launchpad.net/openstack-chef/+spec/db2-support

Oslo: https://blueprints.launchpad.net/oslo/+spec/openstack-db2-support

Nova: https://blueprints.launchpad.net/nova/+spec/db2-database

Cinder: https://blueprints.launchpad.net/cinder/+spec/db2-database

Glance: https://blueprints.launchpad.net/glance/+spec/db2-database

Keystone already has the support: https://github.com/openstack/keystone/commit/052e7d525146c235f3c4ddc729ee6e1ac18a1337

============

Note that the patches are already available, they just need to be pushed up to OpenStack.

Whiteboard

The project does not appear to be on a milestone schedule, but we'd be targeting icehouse-1 since this is a pre-req for the other core projects having DB2 support.
