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
I don't know what this field actually does. This is the config that I uploaded to the repo and it seems to be fine.
