Minor cleanup

- remove unused variable
- fixed indentation
- Get the floating network's VLAN id from the correct value of the network
  attribute. It doesn't make a real difference as the public and floating VLANs
  need to be the same currently. But this is cleaner.
Re-arranged generation of provider network options

There should be no difference between provider networks generated for
linuxbridge or openvswitch setups, when using the "VLAN" networking modes.

Previously we didn't add any --provider options in openvswitch based setups.
Which cause the segmentation_id attribute to be auto-populated with a wrong
value.
Honor the :use_vlan flag when creating the floating network

If use_vlan is false for the floating network we need to create the floating
network with type "flat". Otherwise it will endup being tagged to a VLAN and be
inaccessible from the public network (especially when using linuxbridges).

ha: Make neutron-ha-tool start after haproxy and neutron-server

Otherwise, neutron-ha-tool fails to start.

Of course, we only do that when neutron-server and neutron-l3 roles are
on the same cluster, and both with HA.

Don't use the "router" range anymore for the "fixed" network

Neutron is able to allocate the router address automatically from the
allocation pool.

move all authtoken config options to neutron.conf

We can rely on the upstream api-paste.ini file. Since we're not
modifying it there's no need to manage it with Chef.
