id can be set in the post body with v2

[Vinod Mangalpally]

I used MySQL with BIND for these tests.
For a POST at /v2/zones with a body as below
{
  "zone" : {
    "id" : "2a1d1d1d-1324-4a80-aa32-1f69a91bf2c8",
    "pool_id" : "2b1d1d1d-1324-4a80-aa32-1f69a91bf2c8",
    "project_id" : "my_project_id",
    "status" : "ERROR",
    "ttl" : 12,
    "serial" : 100,
    "version" : 5,
    "created_at" : "2014-02-24T16:16:42.000000",
    "updated_at" : "2014-02-24T16:16:42.000000",
    "name" : "example2.com.",
    "email" : "<email address hidden>"
   }
}

the Response is
{
  "zone":{
   "status":"ACTIVE",
   "description":null,
   "links":{
    "self":"http://192.168.33.8:9001/v2/zones/2a1d1d1d-1324-4a80-aa32-1f69a91bf2c8"
   },
   "updated_at":null,
   "ttl":12,
   "serial":1394645291,
   "id":"2a1d1d1d-1324-4a80-aa32-1f69a91bf2c8",
   "name":"example2.com.",
   "created_at":"2014-03-12T17:28:11.958567",
   "pool_id":"572ba08c-d929-4c70-8e42-03824bb24ca2",
   "version":1,
   "project_id":"noauth-project",
   "email":"<email address hidden>"
  }
}
The id field is updated. pool_id, project_id, status, version, serial, created_at, updated_at can be specified in the body but are ignored.

    Ensure that request body in v2 contains valid fields

    Currently 'id' and other fields like 'created_at' and 'updated_at' can
    be set in the request body. Some of these fields are ignored and
    some like 'id' can actual set the id.
    With this change - remove 'id' from the list of valid keys and ensure
    that only valid keys are present in the request body.
