Subject: [PATCH] Add support for `ensure => latest`

Currently it is not possible to update the extracted tarball once it exists. Specifically, the following does not work:

```
s3file { '/tmp/my_archive.tar.gz':
  ensure => 'latest',
  bucket => 'my_s3_bucket',
  key    => 'my_archive.tar.gz',
  notify => Archive::Extract['my_archive'],
}
archive::extract { 'my_archive':
  ensure     => 'present',
  target     => '/mnt/my_archive',
  src_target => '/tmp',
}
```

This change allows `ensure => latest`, which removes the target directory and extracts the latest tarball.
