Add a RRD Filesize Calculater in the Online Documentation or Checkmk Help

Please add a RRD file size calculator to the "Performance data and graphing" Checkmk documentation https://docs.checkmk.com/latest/en/graphing.html#data_rrds.

This would allow everyone to see how different settings affect the size of the RRD file. Based on these numbers, a simple prediction could then be made for the total storage space required.
