A new Grafana dashboard file rdc_grafana_dashboard_example.json
has been added to the folder python_binding. User can import
this dashboard to monitor multiple compute nodes.
To display the host name only in the dashboard, the
rdc_prometheus_example.yml is also changed to create a new label
short_instance which will not have the port number.
