Sean M. Collins 2a242519f7 Begin new lib/neutron
Background for this work can be read on the mailing list:

http://lists.openstack.org/pipermail/openstack-dev/2016-May/094063.html

Usage of the new Neutron is by setting the following in
ENABLED_SERVICES:

* neutron-api
* neutron-l3
* neutron-agent
* neutron-dhcp
* neutron-metadata-agent

For now, the new neutron library supports just the ML2 plugin, with the
Open vSwitch and Linux Bridge agents supported. All other Neutron
plugins should be creating their own DevStack plugin if they wish for
DevStack to support them. Many of them already do.

Other notable changes compared to neutron-legacy:

* Rely on the Neutron defaults, and force Neutron to make
  sane defaults instead of all kinds of knobs in DevStack.

* Default to rootwrap daemon support

* Use the security group driver by default

* interface_driver can now use NEUTRON_AGENT (linuxbridge, openvswitch), since
  they are entrypoints in neutron's setup.cfg

* Use NEUTRON_AGENT variable to determine which agent to run
  Works with NEUTRON_AGENT set to either "linuxbridge" or "openvswitch"
  Default is openvswitch for the time being.

* Set ML2 configuration for VXLAN support

* Remove Xen hypervisor stuff - it should be a plugin

* Move L3 crud into separate service file:

  There's a lot of L3 configuration that was in the main neutron file, but
  a lot of it is self contained and can be moved into its own file.

  The new l3 service file will contain all the previous L3 plumbing and
  configuration that the OpenStack Gate expects, while also eventually
  moving the whole l3 network creation step into a single hook that can be
  overridden by plugins.

* Introduce a check for a function "neutron_plugin_create_initial_networks" which
  will become the mechanism through which different topologies, and
  networking plugins can create and wire the initial networks that are
  created during a stack.sh run.

The new lib/neutron is considered experimental, and followup patches
will build upon this one. Existing users of lib/neutron-legacy should
remain unharmed.
