docs: Parse the number of datapoints of a query.
          This can be calculated from the given duration and resolution of the query.
          E.g. if the query has a duation of 2*60*60 = 7200 seconds and a resolution of 10 seconds
          then the number of datapoints would be 7200/10 => 7200 datapoints.
