For the data packs, setting the limit for the repackmaxpacksize to be 64 such
that data pack with size 65 is more than the limit. This effectively ensures
that no generation has 3 packs and therefore, no packs are chosen for the
incremental repacking. As for the history packs, setting repackmaxpacksize to be
0 which should always result in no repacking.
