Pass correct clientbuilder to cloudproviders

Fixes https://github.com/kubernetes/kubeadm/issues/425 by moving the Initialize call to after the start of the token controller and passing `clientBuilder` instead of `rootClientBuilder` to the cloudproviders.

/assign @bowei 

**Release note**:
```release-note
NONE
```

Should fix in 1.8 and cherrypick to 1.7
