Add community/mfridman-go-json v1.2.0 (#1029)

This PR adds a new community plugin which supersedes the existing one
mitchellh/protoc-gen-go-json. I've disabled further updates of that
plugin, and will mark it deprecated shortly.

This should also resolve the upstream issue folks have been asking
about. mitchellh/protoc-gen-go-json#17
