Catch AirflowSkipException and allow the solid to return successfully
hmm can we warn here or log an event or something, just so there's some record that we handled this?
prob don't need ui_color for the test :)
Process-wise I'd like for the SkipEvent to be added to the core on its own (without touching airflow) and with use cases and rationale clearly laid out. It should make sense in the absence of Airflow. Adding a top level event type to the system is a whole affair which needs to properly tested, thought through, and flowed down to the graphql layer.
