title: Airflow user creation
body: <p>I am using Airflow version 1.8.2 and set up couple of Dags.Everything running as expected .I have admin user created for airflow web server access.But for other teams to monitor their job we can't provide this admin user So I tried to create a different user from the UI '/admin/user/'.
  But only the following fields are available .No options to provide roles or password etc.

  <p>Does anyone faced the same issue or I am doing some wrong thing .How to create role based users So that I can tag some specific dags to those teams</p>
  
  <p>Thanks</p>
