Automatic merge from submit-queue (batch tested with PRs 66920, 67316, 67363, 67528, 66963). If you want to cherry-pick this change to another branch, please follow the instructions <a href="https://github.com/kubernetes/community/blob/master/contributors/devel/cherry-picks.md">here</a>.

Fixes regression in kubectl logs: the --all-containers=true option didn't work

**What this PR does / why we need it**:

Fixes regression introduced in #66398 and adds unit tests for logging with `--all-containers=true`. See #67314 for more details.

**Which issue(s) this PR fixes**:
Fixes #67314

**Special notes for your reviewer**:

I didn't cover cases with `coreinternal.PodList` and `coreinternal.Pod` in tests, because it doesn't look like we need them: I didn't manage to find any callers of the `logsForObjectWithClient` and `logsForObject` functions, so, probably, we can remove them. I'll double check and try to do that separately once this PR is merged.

**Release note**:
```release-note
NONE
```
