FinOps: additional 150/month - 61GB security / 171GB other volume: Investigate excessive random 1ms frequency security log GKE ClusterManager.ListClusters audit calls causing spike from 0 to $5/day costs for the logging project

https://github.com/GoogleCloudPlatform/pubsec-declarative-toolkit/wiki/FinOps
fixing by turning off VPC flow logs
part of #492
61GB for the security log sink and 171GB for other logs
An idle autopilot cluster all of a sudden after a couple weeks starts incurring $5/day log storage costs with 1ms frequency GKE ClusterManager.ListClusters
This occurs on the logging project as a result of calls in the cluster project - log storage is not billed to the GKE cluster project



Review sink volume of 61GB on the security sink and 171GB on the other logs
