%load_node integration with flowchart - One Click debugging experience

[noklam]

The idea is we can have a per-cell development workflow. We already have %load_node, the challenge there is that it assumes user have a node name (otherwise it's not a human readable name).

With the extension, we may auto-generate the name so it won't be a blocker. The flow will be:

1. User click on a node
2. Hit Debug Node
3. It populate a notebook that has %load_node <node_name>
4. User run the cell to get all necessary code & data (better if we can automated this, not sure)
5. Debug in the notebook sandbox.
