Yusuke KUOKA a31757ae07 Purge releases on deletion
So that we can just reuse release names after `helmfile delete`.

This is verified to work by confirming that `helmfile delete` does add `--purge` flag to `helm delete`:

```
$ helmfile delete
exec: helm delete --purge brigade-project
release "brigade-project" deleted
```

And by confirming that I can now re-install releases from the same charts.yaml without any modification of release names:

```
PROJECT=deis/empty-testbed ENV=staging IMAGE=mumoshu/golang-k8s-aws:1.9.1 COMMAND='go' SERVICE_ACCOUNT=default helmfile sync
Release "brigade-project" does not exist. Installing it now.
NAME:   brigade-project
