json.hpp wants it, but it isn't always available. Rather than patch json.hpp directly to remove the dependency, provide a json.h wrapper header that subs in std::experimental::string_view using preprocessor magic. All the consumers of json.hpp are in src/web_service, so the wrapper header is placed there as well.
