FamilyScanDurationsMap Calculate the logarithmic fit of each family base on static measurements of family scan duration in seconds per scanSizesGB value. The tests were made on a t2.large instance with a gp2 volume. The times correspond to the scan size values in scanSizesGB. TODO add infoFinder family stats. nolint:gomnd
