CAMEL-25517: http-client keeps the order id, sku and quantity in variables
(#104)
Camel favours variables for the values a route keeps for itself: like
exchange properties they stay
in the route (headers would travel on the HTTP request), and the README and
the step-by-step prompt
now say variables too.

headers travel on the

parameter on the server side.

- The body is set to null before the call: a GET has no body, and the order
