title: Using ambassador authservice to only require basic auth on some routes/urls (or services)
body: <p>I want to activate ambassador authservice to only require authentication on certain routes/urls. Now if you install the basic http auth service it requires this auth for all services by default. So how can I configure ambassador or the auth service (separate service with ExAuth) to only require auth on certain routes/urls?</p>
  
  <p>Ambassador version 0.51.2
  kubernetes version 1.14
  auth service I am using as base: <a href="https://github.com/datawire/ambassador-auth-httpbasic" rel="nofollow noreferrer">https://github.com/datawire/ambassador-auth-httpbasic</a></p>
