worker/containerd: expose namespace and UUID as labels 

e.g.,
```
Labels:
        org.mobyproject.buildkit.worker.containerd.namespace:   buildkit
        org.mobyproject.buildkit.worker.containerd.uuid:        343cfb49-cce9-453f-b21c-e5d22ca2cb47
        org.mobyproject.buildkit.worker.executor:               containerd
        org.mobyproject.buildkit.worker.hostname:               suda-ws01
        org.mobyproject.buildkit.worker.snapshotter:            overlayfs
```

Planned to be used by nerdctl to detect whether containerd exporter can be used
