Adding agent service sub command for Windows

[luthermonson]

adds the service subcommand to agent which can add/delete a windows service for rke2 via the windows service manager. the agent will only work with a config yaml so --config is a required param and get's passed/set on the service via args so ultimately the call to run the agent will default to rke2 agent --config /etc/rancher/k3s/config.yaml

Should this functionality be added to k3s and carried into RKE2? That's what we did for the etcd subcommands. Also, take a look at how the etcd subcommands are and try to mirror that approach for consistency's sake.

ya we already had this convo, no one committing to windows in k3s so no point in the commands there. i agree it SHOULD be there but that requires us to get to a point where k3s works in windows too

Fair enough. I had forgotten about that convo.
