All specs are passing in all gems and in test-app
Properly generates open api 3 swagger via rake rswag:specs:swaggerize and via bundle exec rspec in test-app dir
Adds to swagger_Formatter to remove injected body parameters since those are 2.0 and ont 3.0 compliant
Adds to example_group_helpers to only automatically save request examples in the swagger output on 2xx response, since otherwise it was getting clobbered
