[OVN] Use the MySQL backend for the `TestOvnNbSync` tests

Browse Source 
The ``TestOvnNbSync`` test cases perform intensive operations on both
the Neutron database and the OVN databases. These test are frequently
hitting an issue with the Neutron database, that in the functional test
is, by default, SQLite.

When a port is being deleted, the database raises an exception with the
following message:
  DELETE failed.: oslo_db.exception.DBReferenceError:
  (sqlite3.IntegrityError) FOREIGN KEY constraint failed
  [SQL: DELETE FROM ports WHERE ports.id = ?]
  [parameters: ('64720ac5-72a0-4e88-8193-fd54a97ccef3',)]

This resource (port) and the one referring to it (floating IP), have
been created and updated in previous API calls, thus the transactions
to the database should be commited and finished.

This patch is changing the database backend to MySQL, that should
provide better transaction isolation.
