Subject: [PATCH] Run "helm init --client-only" in Dockerfile (#907)

In trying to use the base quay.io/roboll/helmfile image to deploy a chart that depended on an external repository, I ran into this error:

```
Adding repo bitnami https://charts.bitnami.com/bitnami
in ./helmfile.yaml: in .helmfiles[0]: in dirac/helmfile.yaml: helm exited with status 1:
  Error: Couldn't load repositories file (/root/.helm/repository/repositories.yaml).
  You might need to run `helm init` (or `helm init --client-only` if tiller is already installed)
```

The minimum to work around that error would be approximately:

```
mkdir /root/.helm/repository && echo apiVersion: v1 > /root/.helm/repository/repositories.yaml
```

Though there might be other things that I'm unwittingly depending on in the base `helm init`, it should be more friendly if we just run `helm init --client-only` while building.
