Add DVR support to DevStack

This patch introduces a new Neutron  config option: Q_DVR_MODE.

The possible values are:

- legacy  : No DVR functionality
- dvr_snat: Controller/single node DVR
- dvr     : Compute node in multi-node DVR

When DVR is enabled the following configuration changes will be
in place:

- neutron.conf
  - router_distributed=True

- l3_agent.ini
  - agent_mode=$Q_DVR_MODE

- ovs_neutron_plugin.ini:
  - enable_distributed_routing=True
  - l2_population=True
  - tunnel_types=vxlan

Supports-blueprint: neutron-ovs-dvr

Remove unfubar_setuptools

It is no longer used for anything, nor does it seem to be
needed in the modern world of get-pip.py.

Add SERVICE_TOKEN to the sample local.conf

I expect the sample local.conf file to contain all the required
variables. However, after copying samples/local.conf, the stack.sh
script still asks for SERVICE_TOKEN.

This commit adds the SERVICE_TOKEN definition to local.conf so that a
new user can just copy samples/local.conf, edit it, and have a running
stack.sh without the mild annoyance of having more variables to set.

Add conntrack-tools to nova dependencies

'Error deleting conntrack entries' appears in all
n-net. Adding conntrack-tools/conntrack as nova dependency,
in order to eliminate this issue.

Remove output filter on rabbitmq install

The original workaround was for an init script that grabbed stdout.
This was some time ago and I think it's safe to remove.

It can be a problem on Fedora; out-of-the-box some old F20 images can
have a broken dependency when rabbitmq installs.  With this in place,
all helpful output goes into the temp log file, but it is never shown
because the install_packages function exits the script.  Thus things
just stop and you have no idea why.

stop leaking service as a global var

the tls code was leaking out $service as a global variable, which
was causing all manner of confusing errors in grenade trying to
use that variable name. All lower case vars should be localize.

add is_keystone_enabled

This is missing, and makes logic much harder for the grenade use
case.
