DDF-2644 Update convex hull to be transparent, remove z-index adjustment from cesium points

 - Previously it was the same color as the cluster it belonged to.  Since there isn't a "with certainty" method to make sure that points are above their convex hull in Cesium, it is now transparent.
 - Z-index adjustment has been removed from cesium points.  This was an attempt to make them appear above convex hull outlines, but it ended up causing issues at extreme zoom levels (points would disappear prematurely).
