Imports existing measurement data from Peass CLI usage, which need to contains
staticTestSelection_$project.json
traceTestSelection_$project.json
statistics.json
changes.json
into a format readable by the Peass-CI plugin.
Stores results of one RTS run - it is necessary to store these reduced data instead of StaticTestSelection, so not all data get persisted for every commit (otherwise, this would be a lot of data).
