[Openstack] [Fuel] add custom settings to a fuel deploy

Hi Jim,

There are a couple of ways to approach your problem:
1. Implement Fuel Plugin, where the plugin would automatically override
changes done by Fuel core tasks [1], you can override or skip any task from
deployment graph.
2. Fix puppet manifests in place, the manifests which are used for
deployment are located in "/etc/puppet/" directory on Fuel Master node,
during the deployment they are synced to OpenStack nodes via rsync. You
should grep for nova_config, keystone_config, etc, to see where the
parameters your are looking for are located, do not forget to put it under
git so you can keep track of your changes.

Thanks,
