Usability improvements and godep updates

1. Updating godeps
2. Placed all the manifest files under deploy/ and updated the Readme.
3. Updated grafana to start with a default dashboard with pod and label based graphs.
4. Updated Readme to use kubectl.sh instead of kubecfg.sh
Might be useful to add versioning policies here. Is every release an increment of 0.1, or you want to make a convention?
