reqwest 0.13.0-rc.1 on Rust Cargo

👀 Discussion here if you give it try, thanks!

Main breaking changes

rustls is now default instead of native-tls
rustls provider defaults to aws-lc instead of ring (rustls-no-provider exists if you want to enable a different one)
rustls-tls renamed to rustls
rustls roots features removed, platform-verifier is used instead
- To use different roots instead, use tls_certs_only(your_roots).
Many TLS-related methods renamed, but previous name left in place with a "soft" deprecated (just documented, no warnings).
query and form are now crate features, disabled by default
Long-deprecated methods and crate features have been removed.
