feat: add --kubelet-args to scheduler-k3s:initialize

Browse Source 
The server node created by `scheduler-k3s:initialize` had no way to receive kubelet arguments, unlike nodes joined through `scheduler-k3s:cluster:add` or configured via `scheduler-k3s:profiles:add`. This meant settings such as `allowed-unsafe-sysctls` were unreachable on a single-node install.
