CSIT-1110: Integrate anomaly detection into PAL
+ Keep the original detection, + add the new one as subdirectory (both in source and in rendered tree). - The new detection is not rebased over "Add dpdk mrr tests to trending". New detection features: + Do not remove (nor detect) outliers. + Trend line shows the constant average within a group. + Anomaly circles are placed at the changed average. + Small bias against too similar averages. + Should be ready for moving the detection library out to pip.
