title: Does prometheus read the file with token EACH TIME it makes a request?
body: <p>I am going to integrate alerting functionality of prometheus soon. The app I'm working on changes pool of authorised tokens each hour. I wonder if it is <strong>MY</strong> responsibility to make a post request on <code>reload</code> endpoint and trigger reloading of the configuration or maybe prometheus will do it itself? I'm not sure how to make prometheus use the latest token.</p>
  
  <p><em>Additional question if prometheus does it itself:</em></p>
  
  <p>Does it reload token on 401 http error or maybe each time it makes a request?</p>
