Launch Operator trigger_rule Option

[leungadrian]

Currently the launch operator defaults to 'all_success' and it doesn't appear to have an option to pass trigger_rule's to this operator. Thus when any task upstream is skipped, the launch task skips and linked tasks fail, despite differing trigger_rule's applied to the DatabricksNotebookOperator's.

Is it possible to pass trigger_rule's to this Operator, and if not can this functionality be added?
