#430 Upgrade webmock and tests

[bobbrodie]

Overview

The goal of this pull request is to upgrade to webmock 3.x. There are a few changes necessary to accomplish this:

• Update webmock
• Update how we implement authenticated calls

Notes

The number of tests reported will drop, due to what I can tell are duplicates running in v1. Looking at the examples below, you'll see that webmock v1.x was running the shared tests twice. This has been remedied.
