This patch removes the Neutron capability of creating database tables from sqlalchemy models for all those model classes for which a table is not found in the database schema. Migrations should be the official and only solution for creating and managing the Neutron db schema. This patch also adapts unit tests in order to ensure test schemas are still correctly created. DocImpact Update deployment documentation accordingly. Closes-Bug: #1207402 Change-Id: Ie4ee5507888ecad5f6dc32ce7a029c43014687a2 Co-Authored-By: Henry Gessau <gessau@cisco.com>
