Implement Cargo HTTP index (#24452)

Browse source 
This implements the HTTP index
[RFC](https://rust-lang.github.io/rfcs/2789-sparse-index.html) for Cargo
registries.

Currently this is a preview feature and you need to use the nightly of
`cargo`:

`cargo +nightly -Z sparse-registry update`

See https://github.com/rust-lang/cargo/issues/9069 for more information.
