Winson Chan 59830a49f1 Sync code with oslo-incubator
Updated openstack-common.conf and remove outdated modules. Ran update script
in oslo-incubator to generate modules in the mistral/openstack and tools
directories. Sqlalchemy backend has changed significantly in oslo-incubator.
Refactored mistral db api to address these changes and updated the base test
class DbTestCase accordingly.
