This enables the usage of the mysql_enable_ndb setting
in oslo_db from bug 1564110. This allows operators to
select from MySQL (InnoDB) or MySQL Cluster (NDB)
as the storage engine backend. There are only two
tables that need to have their columns auto adjusted
to fit with in the 14k row width limit of NDB, cluster
and cluster_templates. The modifications here will
have zero affect on users of MySQL (InnoDB). Additionally,
this fix will auto adjust those tables in models.py
module to support this enhancement.
