Http agent doesn't parse other JSON-format Content-Types

As documented, the "Convert to JSON" option will only parse the body if the Content-Type is application/json. However, there are many other content types that use the JSON format, indicated by a +json suffix (just as +xml is used to indicate XML formats). For example, application/vnd.spring-boot.actuator.v2+json.

It would be very useful if the HTTP agent would also parse these bodies.
