Add host to known_hosts file without prompt
<p>I am trying to add a known host to the known_hosts file using ansible</p>

<pre><code>vagrant@jedi:/vagrant$ ansible web -m known_hosts -a "name=web state=present"

paramiko: The authenticity of host 'web' can't be established.
The ssh-rsa key fingerprint is afb8cf4885468badb1a7b8afc16ac211.
Are you sure you want to continue connecting (yes/no)?
</code></pre>

<p>I keep getting prompted as above.</p>

<p>I thought this module took care of this? Otherwise I should do a keyscan of <code>web</code> and add that to the known_hosts file. </p>

<p>What am I doing wrong or misunderstanding?</p>
