[Rule] New required property added to request

[vishrutshah]

If a new property is made required in the request body, clients will have no way to set this and the request will fail.

Example:

{
  "id": "1034",
  "message": "The new version has a new required property 'type1' that was not found in the old version.",
  "jsonref": "#/definitions/StorageAccountCheckNameAvailabilityParameters/properties",
  "json-path": "#/definitions/StorageAccountCheckNameAvailabilityParameters/properties",
  "type": "Error"
}
