Add files-container option for stack create and update

If files-container option is specified:

- All template/env files would be fetched by the heat engine
  relative to the files_container and no local files other
  than the root template would be sent to server.
- Relative path of environment files would be sent in the
  environment_files list.

Also adds the option to template validate.
