GCE: Create cloud-provider roles and bindings via addons

**What this PR does / why we need it**:
This removes the `cloud-provider` role and role binding from the rbac boostrapper and replaces it with a policy applied via addon mgr. This also creates a new clusterrole allowing the service account to create events for any namespace.  

**Special notes for your reviewer**:
/assign @bowei @timstclair 
/cc timstclair

**Release note**:
```release-note
GCE: A role and clusterrole will now be provided with GCE/GKE for allowing the cloud-provider to post warning events on all services and watching configmaps in the kube-system namespace.
```
