This change 'rehomes' model_base.py from neutron. This is not quite a verbatim copy due to the following differences: - The field sizes for columns are replaced with the new constants from neutron_lib/db/constants.py - The tenant_id deprecation message is adjusted slightly. - The StandardAttribute table is not included. We also add some base classes and fixtures for DB unit tests. Partially Implements: Blueprint neutron-lib Change-Id: I2087c6f5f66154cdaa4d8fa3d86f5e493f1d24d9
