Doug Wiegley 2eb31f84c9 Fix performance regression adding rules to security groups 
Sometime between liberty and pike, adding rules to SG's got
slow, and slower with every rule. Streamline the rule create path,
and get close to the old performance back.

Two performance fixes:
1. Get rid of an n^2 duplicate check, using a hash table instead,
on bulk creates. This is more memory intensive than the previous loop,
but usable far past where the other becomes too slow to be useful.
2. Use an object existence check in a few places where we do not
want to load all of the child rules.

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).
