[libvirt] [PATCH] docs: formatdomain: Document the CPU feature 'name' attribute

[Kashyap Chamarthy]

Currently, the CPU feature 'name' XML attribute, as in:

    [...]
    <cpu match='exact'>
      <model fallback='forbid'>IvyBridge</model>
      <vendor>Intel</vendor>
      <feature policy='require' name='pcid'/>
    </cpu>
    [...]

isn't explicitly documented in formatdomain.html.

Document it now.

         <span class="since">Since 0.8.5</span> the <code>policy</code>
         attribute can be omitted and will default to <code>require</code>.

+        Individual CPU feature names can be specified as part of the
+        <code>name</code> attribute. The list of known CPU feature
+        names (e.g. 'vmx', 'cmt', et cetera) can be found in the same
