    [FLINK-7575] [WEB-DASHBOARD] Display "Fetching..." instead of 0 when IO metrics are not
yet retrieved

    ## Problem
    IO metrics is the web-dashboard are retrieved asynchronously. When we display a job's
IO metrics for the first time, the API return "0" because values are not yet available. It's
misleading.
    
    ## Fix
    There is now a new flag is the API called *metrics-fetched*. If its value is **false**,
the dashboard displays "Fetching..." instead of 0.
