title: Display only endpoints available to user in Swagger after his login
body: <p>I would like to setup the follownig workflow:</p>
  
  <ol>
  <li>Initially, without login, Swagger shows only 2-3 endpoints - this will be done by providing limited openapi3 json from backend, no problem;</li>
  <li>User logs in via Authorize button (works, openapi3 json has necessary info);</li>
  <li>After login, Swagger emits one more request with user credentials, backend provides new openapi3 json with endpoints available to this specific user and Swagger redraws the page with new data. Preferably, user is still logged in.</li>
  </ol>
  
  <p>Is it possible to do Item 3 with Swagger? How can I manually emit request from Swagger with OAuth2 bearer token (since user logged, token must present somwhere) and redraw Swagger page?</p>
