hey, can you validate my approach? I've created a pulumi configuration that creates couple of resource in Azure and some deployments\service in k8s. I want to run that configuration in a pipeline for each branch developers build (so they can test their stuff). Am I correct in assumption that I need pulumi stack init for each deployment so they dont collide? also, how do I delete pulumi resources and stack afterwards (assuming build agents got no state). also, how do I auth silently to pulumi state server (I wonder if I even need that, since I dont really manage state, I just create stuff and at some point in time I need to clean it up).
