title: HttpRequest different timeouts per flow
body: <p>i am trying to make two http requests with different timeouts per flow, i know i can configure globally httpRequestTimeout in the settings.js file but it sets the timeouts for all the flows.</p>
  
  <p>I have two flows running in the same node-red and i need to set different timeouts for different http requests, i couldn't find a way to achieve it. I tried set the <code>msg.req.timeout</code> and <code>msg.req.socket.server.timeout</code> with no sucess.</p>
  
  <p>Is there any way to acess the variables that are defined on settings.js? Mapping it to a env variable would be good as well.</p>
