Implements minor fixes to the SQL Alchemy scripts in Cinder to support the MySQL Cluster DB. This includes the usage of the boolean mysql_enable_ndb setting from oslo.db from bug 1564110. This allows operators to select from MySQL (InnoDB) or MySQL Cluster (NDB) as the storage engine backend. Additionally, this fixes the models.py to support this enhancement.
