title: Cloud Run disable old revision
body: <p>Is there a way to tell Cloud Run that it shouldn't use an old revision anymore?</p>
  <p>After I deploy a new revision of my service, I'm using the update-traffic command and successfully setting 100% of the traffic to go to the new revision but the UI still shows the old version as &quot;serving traffic&quot;(although it's 0%) which also prevent the latest version to scale up to the max-instances option(which is the real problem).</p>
