title: Stop verbose in ansible.playbook.PlayBook
body: <p>I am using ansible in my CLi. So all error-handling I want to do by myself and I don't want to give extra information that might disoriented  an user.</p>
  
  <p>When I tried to run ansible playbook in python code and I've receive verbose msg's:</p>
  
  <pre><code>PLAY [Role] ***************************************************************
  
  GATHERING FACTS ***************************************************************
  ok: [127.0.0.1]
  
  TASK: [base-devel-go | Install go lang support] *******************************
  ok: [127.0.0.1]
  </code></pre>
  
  <p>I use <a href="https://github.com/ansible/ansible/blob/fbc525cfb66563eedc2755e363c28206a5dc6e7d/bin/ansible-playbook" rel="nofollow">ansible-playbook</a> as source for my flow. Now I see a lot of verbose stuff. I want hide it but I couldn't find how to do this?:</p>
  
  <pre><code>playbook = params["playbook"]
  inventory = ansible.inventory.Inventory(hosts)
  inventory.set_playbook_basedir(os.path.dirname(playbook))
  
  stats = callbacks.AggregateStats()
  playbook_cb = callbacks.PlaybookCallbacks(verbose=utils.VERBOSITY)
  runner_cb = callbacks.PlaybookRunnerCallbacks(
      stats, verbose=utils.VERBOSITY)
  
  
  params["inventory"] = inventory
  params["stats"] = stats
  params["callbacks"] = playbook_cb
  params["runner_callbacks"] = runner_cb
  
  pb = ansible.playbook.PlayBook(**playbook_params)
  pr = pb.run()
  </code></pre>
  
  <p>I tried to find in <a href="https://github.com/ansible/ansible/blob/fbc525cfb66563eedc2755e363c28206a5dc6e7d/lib/ansible/callbacks.py" rel="nofollow">callbacks.py</a> but my level of python is less to find answer</p>
