Subject: [PATCH] Enable neutron to work in a multi node setup
On the controller node where devstack is being run should create
the neutron network. The compute node should not.
The the case that we want to run a multi-node neutron setup we need
to configure the following (in the case that a plugin does not
have any agents running on the compute node):
ENABLED_SERVICES=n-cpu,neutron
In addition to this the code did not enable decomposed plugins to
configure their nova configurations if necessary.
This patch ensure that the multi-node support works.
