Fails to build on systems with OpenSSL 1.1.1

[GabrielMajeri]

I tried to build this from source, but I ran into sfackler/rust-openssl#987, since my system has OpenSSL 1.1.1, and only rust-openssl version 0.10 or greater supports it.

Unfortunately, there are a ton of dependencies that have to be updated to allow the openssl transitive dependency to be updated:

• nativetls
• hyper (for hyper-tls 0.3.0 or newer)
• tokio
• hubcaps (their fix for OpenSSL hasn't even been published to crates.io yet)

That's unfortunate! It uses the macOS native libraries for me, so I wouldn't see this, and I assume that the musl build has an older OpenSSL.

I have a local branch that upgrades hubcaps for other reasons though: https://github.com/integer32llc/rust-playground/tree/upgrade-hubcaps

Would you give that a shot and see if that helps?

[GabrielMajeri]

@shepmaster Yep, that branch works for me.

@GabrielMajeri cool! Then what I'd ask for now is to do your development on top of this branch, but submit your PR against current master (we'll trust CI to make sure it works). I want to do a bit deeper testing of these changes before merging.
