Automatic merge from submit-queue (batch tested with PRs 41121, 40048, 40502, 41136, 40759)

Remove deprecated kubelet flags that look safe to remove

Removes:
```
--config
--auth-path
--resource-container
--system-container
```
which have all been marked deprecated since at least 1.4 and look safe to remove.

```release-note
The deprecated flags --config, --auth-path, --resource-container, and --system-container were removed.
```
