Upgrade `hyper` for `futures` 0.3

[MOZGIII]

As part of the https://github.com/timberio/vector/issues/1142, upgrade hyper to v0.13+.

---

Here's a list of dependencies that are themselves blocked on tokio 0.1:

• goauth - https://github.com/durch/rust-goauth/issues/8
• shiplift - https://github.com/softprops/shiplift/issues/185
• ./vector/lib/tracing-metrics - we'll take care of it

Crates that are ready for the upgrade:

• hyper
• hyper-tls
• hyper-openssl
• reqwest
• rusoto_*
• kube
• hyperlocal
• warp

Overall, not that bad.

The sink side of this has been done and you can find the implementation in http2. Source and Prometheus sinks that use wrap will still need an upgrade.

@ktff this is part of our Tech-Debt Payment #1: Move to Tokio 0.2/Futures 0.3 Project. I'm assigning just this issue to you. I've assigned #2118 and #1142 to @fanatid. I'm assuming this work won't conflict. If it does, let me know and we can try to reassign issues in a way that doesn't.

[ktff]

@fanatid can you prioritize updating src/sinks/aws_cloudwatch_logs/mod.rs to use src/sinks/util/rusoto2.rs instead of src/sinks/util/rusoto.rs. With that and #2808 being merged, we'll be able to finish the upgrade of hyper and hyper-openssl.

[fanatid]

Sure, it was done in #2777 but need move to new PR, should be ready soon.
