Matthew Kassawara 117606139c Install: Neutron updates for Mitaka
Update neutron content for Mitaka.

1) Change 'public' to 'provider' and 'private' to
   'self-service' to improve distinction between these
   networks using neutronish terms.
2) Remove explicit installation of some packages due to
   dependency fixes.
3) Remove explicit configuration of verbosity.
4) Remove explicit configuration of ARP spoofing protection.
5) Remove extraneous configuration for the metadata agent.
6) Remove extraneous configuration for nova-neutron
   interaction.
7) Reduce discussion of MTU because Mitaka fixes most
   of the issues, but we still need to explain the
   most limitation of overlay networks.
8) Generally improve wording.

Networking Option 2: Self-service networks
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Configure the Networking components on a *compute* node.
Configure the Linux bridge agent
--------------------------------
The Linux bridge agent builds layer-2 (bridging and switching) virtual
networking infrastructure for instances and handles security groups.
* Edit the ``/etc/neutron/plugins/ml2/linuxbridge_agent.ini`` file and
complete the following actions:
* In the ``[linux_bridge]`` section, map the provider virtual network to the
provider physical network interface:
.. code-block:: ini
[linux_bridge]
physical_interface_mappings = provider:PROVIDER_INTERFACE_NAME
Replace ``PROVIDER_INTERFACE_NAME`` with the name of the underlying
provider physical network interface. See :ref:`environment-networking`
for more information.
* In the ``[vxlan]`` section, enable VXLAN overlay networks, configure the
IP address of the physical network interface that handles overlay
networks, and enable layer-2 population:
.. code-block:: ini
[vxlan]
enable_vxlan = True
local_ip = OVERLAY_INTERFACE_IP_ADDRESS
l2_population = True
Replace ``OVERLAY_INTERFACE_IP_ADDRESS`` with the IP address of the
underlying physical network interface that handles overlay networks. The
example architecture uses the management interface to tunnel traffic to
the other nodes. Therefore, replace ``OVERLAY_INTERFACE_IP_ADDRESS`` with
the management IP address of the compute node. See
:ref:`environment-networking` for more information.
* In the ``[securitygroup]`` section, enable security groups and
configure the Linux bridge :term:`iptables` firewall driver:
.. code-block:: ini
[securitygroup]
...
enable_security_group = True
firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver
