CNDB-15703: Fix ScoreTracker impl init and reset methods

[michaeljmarshall]

This PR returns the behavior of the ScoreTracker to before #501. There are two issues:

1. The RelaxedMonotonicityTracker had a fixed size bestScores at new BoundedLongHeap(100). The previous behavio used a size that varied based on the rerankK for the query. Further, when the reset method is called, we do not update the size, and as such, we end up with a mismatched bestScores heap, which can result in an incorrect understanding of the worstBestScore in the shouldStop method. In cases where the rerankK is lower than 100, we will search deeper into the graph while in cases where it is above 100, we may return early.
2. The ScoreTrackerFactory#getScoreTracker has enough information to initialize more correct versions of the trackers, so I do that.

@eolivelli - I am adding tests this morning. I found the fix at the very end of my day yesterday and wanted to push something up, though as we can see, it wasn't a global fix since I used the wrong value for the setMaxSize value.
