[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.
