clientIp is now computed from varnish and sent as IP. We should add this to webrequest and remove our client Ip calculations when we refine data.
Tested wiht hive: Over a few hours, there are only a very small amount of requests on which the client IP sent by varnish differs from the one computed on the cluster.
@BBlack reviewed those diffs, and the IP sent by varnish is actually a better approximation of the real client IP than computed on the cluster.
We should merge the code and deploy whenever.
