Automatic merge from submit-queue Allow ABAC to be disabled easily on upgrades **What this PR does / why we need it**: Adds a local variable to the configure-helper script so that ABAC_AUTHZ_FILE can be set to a nonexistent file in kube-env to disable ABAC on a cluster that previously was using ABAC. @liggitt @Q-Lee
Container-VM Image
Container-VM Image is a container-optimized OS image for the Google Cloud Platform (GCP). It is primarily for running Google services on GCP. Unlike the open preview version of container-vm, the new Container-VM Image is based on the open source ChromiumOS project, allowing us greater control over the build management, security compliance, and customizations for GCP.
