rest-client 2.1.0 support

[Fitzsimmons]

Describe the problem you'd like to have solved

rest-client 2.1.0 was released in August 2019. The latest version of ruby-auth0 does not support it. This means that for projects that are already using the latest version of rest-client, the most recent supported version of ruby-auth0 is 4.8.0 (August 01, 2019)

Describe the ideal solution

The latest version of rest-client is supported.

Alternatives and current work-arounds

For users of the auth0 gem:

• Stay on auth0 4.8.0 forever, missing out on any improvements
• Downgrade rest-client to 2.0.x in our project
• Switch to an alternative http client library in our project
• Fork ruby-auth0 and implement rest-client 2.1.0 support ourselves
• Abandon ruby-auth0 entirely

There are plenty of workaround options but they they have high development and/or maintenance costs relative to the benefits.

For auth0

• Abandon rest-client in favour of Net::HTTP, eliminating the dependency on a gem that might have conflicts with gems already installed in client projects

Hey @Fitzsimmons we would love to support rest-client 2.1.0 in the library. There was a PR raised to bump the gem, but several tests were broken. I currently don't have bandwidth to resolve the issue, but I should have some time coming up soon to investigate what the issue was.

Hi @davidpatrick, thanks for the fix. Would it be possible to push the 5.6.0 tagged release of auth0 to rubygems so that this restclient 2.1 update is available as an official version?
