PackBitmapIndex: Set distance threshold 

Setting the distance threshold to 2000 in PackWriterBitmapPreparer to
reduce memory usage in garbage collection. When the threshold is 0, GC
for the msm repository would use about 37 GB memory to complete. After
setting it to 2000, GC can finish in 75 min with about 10 GB memory.
