Display config on visualization

[zilto]

Visualizations now display the config value instead of type Any. Also, nodes affected by configuration have the suffix node_name: config_key.

While working on this feature, I realized all high-level viz function except display_all_functions() failed to show config nodes (#832). This is because it's the only function to pass the config via the nodes argument (type hamilton.node.Node) while other functions first filter a path of nodes, which excludes the config.

Instead of a large refactoring, hamilton.graph.create_graphviz_graph() now has a kwarg config which raises an exception if left to None. It's the caller's responsibility to have this config match the actual config value that lead to the set of nodes passed. This unlikely to cause problem unless people dig into internal APIs.

Changes

• added config kwarg to create_graphviz_graph() and upstream callers
• modified to create_graphviz_graph() display config nodes
• added tests for low-level FunctionGraph.display() and high-level Driver.display_ and Driver.visualize_
• updated tests to use the create_graphviz_graph() config kwarg
