<br>
I synced up with Alex about comments we got at PTG.  It's a long <br>
discussion, I might lost something.<br>
<br>
What i got lists below,  fix me:<br>
<br>
*  Remove sockets<br>
*  Remove thread_policy<br>
<br>
Not sure about following comments:<br>
<br>
<br>
*  Remove the cpu topology from the proposal?<br>
*  Using the cpu pinning info instead of cpu set?<br>
<br>
<br>
By apply the suggestion, the API ``GET /servers/{server_id}/topology``  <br>
response gonna to be like this,<br>
