Action to fully expand lineage of a node, or whole model

[chris-braidwell]

Describe the feature

When I choose a model and look at its lineage diagram, I'd like an option to:
(1) fully expand from the current node to all its ultimate children
(2) fully expand from the current node to all its ultimate parents
(3) fully expand the entire model (not anchored on the one model)

In other words, mimic the +model and model+-style selectors dbt supports for ancestors and descendants.

Describe alternatives you've considered

This can be done in the new UI by selecting models, clicking the "Expand" button to add adjacent parents and children, then click into each parent and child added and expanding THEIR parents and children iteratively until no new ones arise.

Who will benefit?

Anyone who needs to browse lineage would find this helpful.
