There are 3 sets of changes:
1. Create_graphviz_graph(): added logic to highlight path in red
2. Driver visualizations: expose the new params (show_legend, orient, hide_inputs, deduplicate_inputs) to all visualization functions
3. Path visualizations (between, upstream, downstream): previously, the viz would display the set of nodes + their immediate parents. The driver function would only pass the "nodes on the path" and have the viz draw the parents. This caused an issue because nodes not explicitly passed didn't received styling. Instead, they were implicitly created when trying to create to them. The changes force the parameter strictly_display_only_passed_in_nodes=True and handles the nodes to pass at the Driver level.

To use new rendering.

So that they now match the new way things are rendered.
