The first changeover of a launch_run callsite. This should be safe to land, because with the LaunchImmediateRunCoordinator as default, changing the call site just adds a layer of indirection.
Not familiar with grapqhql or dagit tests, could use some pointers here. I assume there is an existing test for launch_pipeline_execution in graphql but I haven't found it.
Manually: verified that both Coordinators can be used to launch runs from Dagit
