Upstream: available in master and stable branches from stable/queens onwards

    Extended grafana dashboard to display dimensions.
    
    Before the dimensions on the Metrics tab were hardcoded,
    now they are read from the URL and are filtered based on
    the 'dim_' prefix.
    Furthermore, modified the URL for the Graph Metrics button
    to append dim_ prefix for dimensions.
