ITS: remove CookedTracker and older ClustererTask

[f3sch]

Both have not been run in years and were actually none functional for a long while now. With changing the data input, these are not maintainable anymore (sure one can make them compile superficially but they are not working).

dataflow error is unrelated. From my side this could be merged, but should be checked with ITS experts before. I see also Ruben has already approved it.
