Matthew Kassawara 374a38f49a [install] Initial networking architecture changes

Implement initial networking architecture changes for Liberty
as follows:

1) Remove nova-network.
2) Develop architecture for provider networks with Linux
   bridge agent.
3) Develop architecture for self-service networks with
   Linux bridge agent.
4) Munge the neutron controller and network node configuration
   together.
5) Rejigger neutron to use the Linux bridge agent.
6) Restructure launch an instance content to account for
   two networking options.
7) Other restructuring as necessary to meet the primary
   goal.

For simplicity, both architectures require only two nodes,
each with two network interfaces, to deploy core OpenStack
services. Also, to address recurring issues about the lack
of support for connecting instances directly to the
public/external network, the self-service architecture
augments the provider networks architecture which allows
connection to both private and public networks.

Networking Option 2: Self-service networks

List agents to verify successful launch of the neutron agents:

$ neutron agent-list
+--------------------------------------+--------------------+------------+-------+----------------+---------------------------+
| id                                   | agent_type         | host       | alive | admin_state_up | binary                    |
+--------------------------------------+--------------------+------------+-------+----------------+---------------------------+
| 08905043-5010-4b87-bba5-aedb1956e27a | Linux bridge agent | compute1   | :-)   | True           | neutron-linuxbridge-agent |
| 27eee952-a748-467b-bf71-941e89846a92 | Linux bridge agent | controller | :-)   | True           | neutron-linuxbridge-agent |
| 830344ff-dc36-4956-84f4-067af667a0dc | L3 agent           | controller | :-)   | True           | neutron-l3-agent          |
| dd3644c9-1a3a-435a-9282-eb306b4b0391 | DHCP agent         | controller | :-)   | True           | neutron-dhcp-agent        |
| f49a4b81-afd6-4b3d-b923-66c8f0517099 | Metadata agent     | controller | :-)   | True           | neutron-metadata-agent    |
+--------------------------------------+--------------------+------------+-------+----------------+---------------------------+

The output should indicate four agents on the controller node and one agent on each compute node.
