Title:
  500 response on booting a server with disk security group argument

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  curl -i http://127.0.0.1:8774/v2/28e0a231507c4dff846cbc4dd6cd814c/servers -X POST -H "X-Auth-Project-Id: demo" -H "User-Agent: python-novaclient" -H "Content-Type: application/json" -H "Accept: application/json" -H "X-Auth-Token: <TOKEN>" -d '{"server": {"name": "server", "imageRef": "bb3048da-0cca-474f-9f05-e04bf176520c", "flavorRef": "42", "max_count": 1, "min_count": 1, "security_groups": {"name": "sec"}}}'
  HTTP/1.1 500 Internal Server Error
  Content-Length: 128
  Content-Type: application/json; charset=UTF-8
  X-Compute-Request-Id: req-87686a62-a4c0-4c46-b873-ff24f87d94e4
  Date: Mon, 14 Oct 2013 14:41:44 GMT

  {"computeFault": {"message": "The server has either erred or is
  incapable of performing the requested operation.", "code": 500}}

  I have modified the curl command from the 'nova --debug boot server
  --flavor 42 --image cirros-0.3.1-x86_64-uec --security-group sec'

  and changed the 
   "security_groups": [{"name": "sec"}]
   part to 
  "security_groups": {"name": "sec"}

  When the nova-api gets a dict instead of list of dict causes a 500
  response.

  The  '"security_groups": "foo"' also causes 500 response.
