Update to Faraday 1.0

[picandocodigo]

Migration to Faraday 1.0.

• We were already using adapter method to set the adapter, so that's 👍
• We were checking handlers for loaded adapters in the specs, I changed them to use Faraday's adapters.
• The client initializer was modified but this should not disrupt final users at all, check 0fdc653 for more information.
• Migrated error checking to remove the deprecated Faraday::Error namespace.
• This change is not compatible with Typhoeus. The latest release is 1.3.1, but it's still using the deprecated Faraday::Error namespace. This has been fixed on master, but the last release was November 6, 2018. Version 1.4.0 should be ok once it's released.
• Note: Faraday 1.0 drops official support for JRuby. It installs fine on the tests we run with JRuby in this repo, but it's something we should pay attention to.

That looks promising! As it also cleansup from "stoned" gem :)
I think that Changelog should also include a message for default change from typhoeus to patron

@lizdeika thanks for taking a look! 😁

The change from typhoeus to patron is only in the documentation example on how to set the adapter. By default, the client will still use the Faraday HTTP library.

I added a note about Typhoeus, hopefully we'll get a new release soon and the issue will go away 😄
