Description
When running dataform run --dry-run, Dataform prints out a list of all actions (tables, views, operations etc) that will be created.
It doesn't consider whether these outputs already exist however, and will recreate all outputs regardless of if they have changed or not. This is OK, but there should be a way to tell when an output will be updated.
Proposal
Add metadata to the output of the dataform run --dry-run that shows what action will be performed for each action in the graph.
Views
For each view that will be created, we should show whether the view definition will be changed or not. The output of --dry-run should show what action we will perform for this view, either update or unchanged.
Tables & Incremental tables
For each table that will be created, we can't currently tell if it needs to be created or not. However, we do know if it already exists.
The output of --dry-run should show for each table the type of action that is being performed, either refresh (the table exists but must be refreshed) or create.
Operations
Operations will always be run, as we don't know their behaviour. Therefore we can always show the action as run.
Assertions
Assertions will also always be run currently, so we can show the action as run.
