I think this may not work in case of GMail, because it uses a custom scheme as a
base URL, so all images will relative URLs will be using that scheme and
presumably will be blocked. Perhaps, switch to using a whitelist approach for
networking schemes instead?

I thought I could reuse this for BlockNetworkLoads but since we are choosing to
blacklist, then that might no longer be the case. For now removed this file and
the changes in url_constants. If similar logic can be reused in
BlockNetworkLoads, then do the refactor then.
