Subject: [PATCH] feat(diff): Pass namespace to helm-diff

Tested manually by running `helmfile diff` with debug logging:

```yaml
helmDefaults:
  tillerNamespace: foo

charts:
  - name: grafana
    namespace: grafana
    chart: stable/grafana
```

```console
$ ./helmfile --log-level debug diff
Comparing grafana stable/grafana
exec: helm diff upgrade --allow-unreleased grafana stable/grafana --namespace grafana --tiller-namespace=foo
```

Resolves #179
