Always display the marker regardless of collision, and hide any
CollisionBehaviorOptionalAndHidesLowerPriority markers or labels that would overlap with the
marker.
Display the marker only if it does not overlap with other markers. Does not include
GMSCollisionBehaviorRequired. If two markers of this type would overlap, the one with the
higher zIndex is shown. Collision rules for markers with the same zIndex is undefined.
