Subject: [PATCH] Drop support for Ruby 2.0, 2.1, and 2.2

These Ruby versions are no longer supported. Including these in our CI
builds slows the feedback cycle and introduces a maintenance burden for
which there is no clear user base.

1. Ruby 2.0 on Februrary 24th, 2016
2. Ruby 2.1 on April 1st, 2017
3. Ruby 2.2 on June 20th, 2018
