Bug Description

Rally version: 0.10.1~dev31
OS: Ubuntu 16.04 LTS

Running the create-and-delete-stack.yaml with the plugin HeatStacks.create_and_delete_stack calling the heat template default.yaml.template

`$ rally task start heat/create-and-delete-stack.yaml --task-args-file args.yaml`

fails with message:

```Reason(s):
 Heat template validation failed on heat/templates/default.yaml.template. Original error message: ERROR: Template not in valid format: Template format version not found..```

create-and-delete-stack.yaml

  HeatStacks.create_and_delete_stack:
    -
      args:
        template_path: "heat/templates/default.yaml.template"
      runner:
        type: "constant"
        times: 5

      context: {}

default.yaml.template

heat_template_version: 2014-10-16

The above version date is available in the openstack template version using

`openstack orchestration template version list` showing

`| heat_template_version.2014-10-16 | hot | |`

I have checked the format of the heat template using `openstack orchestration template validate -f yaml -t heat/template/server.yaml.template` with no errors.

In addition it is perfectly possible to create a stack using this template and the command:
`$ openstack stack create -t heat/templates/default.yaml.template mystack`

```
