Release notes

Highlights

The release adds new plugin for Intel Dynamic LoadBalancer device. The functionality is on part with other plugins: kustomize and DlbDevicePlugin controller based deployments, e2e tests and sample Dockerfiles.

The release also adds improved DSA device provisioning. With an opt-in initContainer cluster admins can setup per-node DSA device configurations using accel-config tool and json templates via ConfigMaps.
