Kevin Benton 72ac25c929 Stop using nested transactions in OVO get/delete 
Nested transactions have unnecessary overhead of starting
new transactions in the database and the only place we need
them are where we expect duplicate violations during create/update.

This gets rid of them for get_objects and delete_objects so we
don't adopt additional unnecessary overhead in OVO adoption. Before
this patch, update_port calls were resulting in several independent
nested transactions that each require multiple round trips to the
database.

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).
