Description

This PR adds a segment for calling any JSON API and displays a json property from the response.
As I have no real experience with go I hope this is ok and valuable for the ecosystem.

This segment can also be updated in the future with more features like authentication, etc.

@mwiedemeyer I want to make this a little bit more generic. I would name it http rather that jsonapi, that way we can execute any http call in the future and also allow to define HTTP method etc...

Hi, thanks, good idea. I've renamed jsonapi to http and also already added the http method as a property. However my go experience is not enough to make it even more generic and add a body, things like that.
Hope you can enhance it even further or use it as it is for now.
