title: How to set connection-timeout in django channel?
body: <p>Django channels disconnect the client if it doesn't respond for few seconds.
  But I can't find where to set that time limit.
  i checked <a href="https://github.com/django/channels/issues/293" rel="nofollow noreferrer">this</a> issue.
  It says it will be configurable.But I can't find where to set that limit.
  thank you</p>
