* Introduce truncating audit backend that can be enabled by passing --audit-log-truncate-enabled or --audit-webhook-truncate-enabled flag to the apiserver to limit the size of individual audit events and batches of events.

### SIG Auth

* RBAC information is now included in audit logs via audit.Event annotations:
    * authorization.k8s.io/decision = {allow, forbid}

* audit.k8s.io api group is upgraded from v1beta1 to v1. ([#65891](https://github.com/kubernetes/kubernetes/pull/65891), [@CaoShuFeng](https://github.com/CaoShuFeng))
    * Deprecated element metav1.ObjectMeta and Timestamp are removed from audit Events in v1 version.
    * Default value of option --audit-webhook-version and --audit-log-version will be changed from `audit.k8s.io/v1beta1` to `audit.k8s.io/v1` in release 1.13

### API Change

- A new field `omitManagedFields` has been added to both `audit.Policy` and `audit.PolicyRule` 
  so cluster operators can opt in to omit managed fields of the request and response bodies from
