text: Title: Method to pass common params to all the nodes in the graph
  Body: **Is your feature request related to a problem? Please describe.**
  There is no way to pass many parameters all at once to each node in a graph. For example, the `verbose` flag would be nice to have it already in all the nodes.
  
  What I am doing now is defining the params inside the `AbstractGraph` (which is inherited in all the scraping graphs) with something like:

  and then pass it in each node explicitily, for example inside `SmartScraperGraph`:

  You may understand that this method doesn't scale up well.
  
  **Describe the solution you'd like**
  I would like a function like this inside `AbstractGraph` that updates all the `node_config` dict for each node:
