Merge pull request #29999 from mtaufen/kubecfg-config-field-rename

Automatic merge from submit-queue

[Kubelet] Rename `--config` to `--pod-manifest-path`. `--config` is deprecated.

This field holds the location of a manifest file or directory of manifest
files for pods the Kubelet is supposed to run. The name of the field
should reflect that purpose. I didn't change the flag name because that
API should remain stable.
