title: How to ignore ansible SSH authenticity checking?
body: <p>Is there a way to ignore the SSH authenticity checking made by Ansible? For example when I've just setup a new server I have to answer yes to this question:</p>
  
  <pre><code>GATHERING FACTS ***************************************************************
  The authenticity of host 'xxx.xxx.xxx.xxx (xxx.xxx.xxx.xxx)' can't be established.
  RSA key fingerprint is xx:yy:zz:....
  Are you sure you want to continue connecting (yes/no)?
  </code></pre>
  
  <p>I know that this is generally a bad idea but I'm incorporating this in a script that first creates a new virtual server at my cloud provider and then automatically calls my ansible playbook to configure it. I want to avoid any human intervention in the middle of the script execution.</p>
