This patch removes the passing of the --containerd argument (value should be path to containerd socket) to kubelet.

This argument is actually not a kubelet argument per se, but instead it is a cAdvisor argument (1) which was accidentally transparently declared and shipped in kubelet a very long time ago, but had been explicitly declared within kubelet and marked deprecated since 2017 (2).
