Wrong version of JSON loaded.

When I try to run the command mutator-graphite.rb, I get the following error:

/opt/sensu/embedded/lib/ruby/site_ruby/2.4.0/rubygems/specification.rb:2278:in `check_version_conflict': can't activate json-1.8.6, already activated json-2.0.2 (Gem::LoadError)

I've attached the output of gem env and gem list for completeness. sensu-gem-env.txt sensu-gem-list.txt

@madelaney thanks for reporting this, any chance you have the time to create a PR to fix this? I solved this in another plugin that you can pretty much likely just copy/paste: https://github.com/sensu-plugins/sensu-plugins-docker/pull/57

@majormoses Happy to help.

I'll work on the fix. Did you want me to port over the README / CHANGELOG changes as well, or just the gemspec change?

[majormoses]

Yes, we require CHANGELOG updates on the PR under ## [Unreleased] and post merge we version it appropriately before it is released. Also we require a testing artifact if you need help with that the easiest thing to test a mutator is to write out an sample event payload and then just cat the file and pipe it to the mutator like this: cat sample_event.json | my_mutator.rb and show the output.
