Release v0.7.0 · containers/nri-plugins

This release of NRI Reference Plugins brings in new features and important bug fixes.

Highlights

Topology-aware and balloons resource policies now support soft-disabling of hyperthreads per container. This improves the performance of some classes of workloads. Both policies support new pod annotation:
```
hide-hyperthreads.resource-policy.nri.io/container.<CONTAINER-NAME>: "true"
```
and the balloons policy has new balloon-type option hideHyperthreads that soft-disables hyperthreads on all containers assigned to a balloon of this type.

The topology-aware policy supports pinning containers to high-bandwidth memory (HBM), or both HBM and DRAM, when pods are annotated with

memory-type.resource-policy.nri.io/container.<CONTAINER-NAME>: hbm
memory-type.resource-policy.nri.io/container.<CONTAINER-NAME>: hbm,dram

Automatic hardware topology hint generation has been fixed in the topology-aware policy. For instance, if a container uses a PCI device, the policy prefers pinning the container to CPUs and memory that are close to the device.
