Title: Find .kitchen.yml by ascending directory from Dir#pwd.

Find `.kitchen.yml` by ascending directory from `Dir#pwd`.

#### For instance:

```
Dir.pwd #=> /foo/bar
File.exist?('/foo/bar/.kitchen.yml') #=> false
File.exist?('/foo/.kitchen.yml') #=> true
```

`/foo/.kitchen.yml` will be used as `project_config`.
