Fixed Storage Used and Capacity Used charts by having them use 'AVG' …

…instead of 'SUM'; Removed the 'Top topFsx NetApp-FSx DataReadOperationTime' and the 'Top topFsx NetApp-FSx DataWriteOperationTime' charts because they didn't show average latency as people might think; Fixed the 'Total Client IOPS' and 'Disk Performance' charts by dividing all metrics by PERIOD; Normalized all the operations per seconds to be based on milliseconds, throughputs to be on MB/s and compacity to be based on GiB/s; Updated labels to be more accurate; Made all the values in the chart to only be at most 2 places behind the decimal point.
