Title:
  stack_create 500 Error with non-string stack_name

Status in heat:
  Fix Released
Status in OpenStack Security Advisory:
  Won't Fix

Bug description:
  When sending a stack create request using the REST API through curl
  with the stack_name parameter set to either a list, or a dictionary a
  Server Error occurs.

  The major problem with this is that when this occurs the response of
  the request will show what database backend the cloud is utilising
  whether it be MySQL, or PostgreSQL. This information could be used by
  a malicious user to exploit the databases. Additionally to the
  database engine being known, the query itself is also printed in the
  response.

  This occurs regardless of the level of logging being set for the heat
  service.

  This has been seen in the master branch as of 12/01/2016.

  I have attached the response of a request with a Traceback.

  The data being sent is the following:
  {
      "files": {},
      "disable_rollback": true,
      "parameters": {
          "flavor": "m1.tiny"
      },
      "stack_name": {"test": "sample"},
      "template": {

              }
          },
