Is there a way to set an http_proxy in a neutron network? Or do I just need to configure this on each instance that needs it?

Issue

• Is there a way to set an http_proxy in a neutron network? Or do I just need to configure this on each instance that needs it?
• My "external" network is xx.xx.xx.xx/24 which is actually internal from the point of view of our organization. In order for any device inside this network to communicate with a device outside of our organization (examples include: yum repositories, remote web services etc) we have to configure a proxy server. We have a proxy server setup in our network that we can use, so this is not something that is broken. The method for configuring a linux server to use this is typically with an environment variable $http_proxy.
• I was merely wondering if there was a way to configure something in neutron that would recognize a request as leaving the organization and immediately forward it to the proxy server rather than needing to configure this on each instance.
