I can't quite figure out how Pulumi is deciding what properties must be defined before import, and which seem to just be optional. If I leave off tags, or listeners, Pulumi yells at me that there's a config difference, but if I leave out subnets, sourceSecurityGroup, securityGroups, idleTimeout, healthCheck, crossZoneLoadBalancing, connectionDraining, connectionDrainingTimeout, or availabilityZones, Pulumi doesn't care.
