Hi k8s folks,

Metrics from kubelet 1.19.2 miss some fields like `container` , `image` , `namespace`:

```auto
container_threads_max{container="",id="/kubepods/burstable/podeb983a4a-14b1-4c8c-b3f1...",image="",name="",namespace="",pod=""} 0 1610711006938

```

I’ve tested different versions. Starting from 1.19.5 issue has gone.  
However I can’t see such bug in [changelog](https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG/CHANGELOG-1.19.md).

In [1.19.5 release notes](https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG/CHANGELOG-1.19.md#changed-2) I can see only `github.com/google/cadvisor: [v0.37.0 → v0.37.2]`.

Then I’ve checked cadvisor release note for v0.37.1 and v0.37.2 but was not able to find a mention of such bug.

Is there a more detailed description of the bug in k8s or cadvisor release notes?
