Updates proxy
-------------
Updates proxy is a service which filter http access to allow access to only something that looks like yum repository (or apt repository in the future - \#887). This is meant to mitigate user errors (like using browser in the template VM), rather than some real isolation. It is done with http proxy instead of simple firewall rules because it is hard to list all the repository mirrors (and keep that list up to date). The proxy is used only to filter the traffic, not to cache anything.

It is done with http proxy instead of simple firewall rules because it is hard to list all the repository mirrors (and keep that list up to date). The proxy is used only to filter the traffic, not to cache anything.
The proxy is running in selected VMs (by default all the NetVMs (1)) and intercept traffic directed to 10.137.255.254:8082. Thanks to such configuration all the VMs can use the same proxy address, and if there is a proxy on network path, it will handle the traffic (of course when firewall rules allows that). If the VM is configured to have access to the updates proxy (2), the startup scripts will automatically configure yum to really use the proxy (3). Also access to updates proxy is independent of any other firewall settings (VM will have access to updates proxy, even if policy is set to block all the traffic).
