There is a analysis [1] suggested to run queries against specific columns rather than full ORM entities to optimize the performance. Right now, it is impossible to execute such optimization because OVO doesn't support fetching specific column yet. This commit introduces a new method 'get_values' in the base neutron object class. Subclass of neutron object can leverage this method to fetch specific field of a OVO. It supports fetching non-synthetic fields only as syntheic fields are not directly backed by corresponding DB table columns. neutron-lib patch: https://review.openstack.org/#/c/619047/ [1] https://review.openstack.org/#/c/592361/ Needed-By: https://review.openstack.org/#/c/610184/ Change-Id: Ib90eae7738a5d2e4548fe9fed001d6cdaffddf3b Partial-Implements: blueprint adopt-oslo-versioned-objects-for-db |

Neutron Objects
Directory
This directory is designed to contain all modules which have objects definitions shipped with core Neutron. The files and directories located inside of this directory should follow the guidelines below.
Structure
The Neutron objects tree should have the following structure:
- The expected directory structure is flat, except for the ML2 plugins. All ML2 plugin objects should fall under the plugins subdirectory (i.e. plugins/ml2/gre_allocation).
- Module names should use singular forms for nouns (network.py, not networks.py).
