  1. Add convenience debugging for HTTP requests in Cargo 

    This is something we probably should have added long long ago given the
number of network issues that arise over time. This adds a new
configuration setting for Cargo, `http.debug`, which activates curl's
`verbose` interface which prints out information like redirects and
headers flying back and forth. This is by default routed through Cargo's
normal debug logging facilities, meaning one way to use this could be:

    CARGO_HTTP_DEBUG=true \
      RUST_LOG=cargo::ops::registry \
      cargo build

and you should get lots of nice verbose logs as a result! This should
hopefully make it much easier to remotely debug HTTP issues as we can in
theory do a lot less guessing and a lot more manual inspection.
