Added logic to strip any existing hyphens before processing the args. (#3662)
Updated the logic to handle if extra args are passed with existing hyphens in the arg. The test was updated to add the additional case of having pre-existing hyphens. The method name was also refactored based on previous feedback.

a62d143936 Fixing various bugs related to windows.
This changes the crictl template for issues with the socket information. It also addresses a typo in the socket address. Last it makes tweaks to configuration that aren't required or had incorrect logic.

6e8284e3d4 rootless: enable resource limitation (requires cgroup v2, systemd)
Now rootless mode can be used with cgroup v2 resource limitations.
A pod is executed in a cgroup like "/user.slice/user-1001.slice/user@1001.service/k3s-rootless.service/kubepods/podd0eb6921-c81a-4214-b36c-d3b9bb212fac/63b5a253a1fd4627da16bfce9bec58d72144cf30fe833e0ca9a6d60ebf837475".

This is accomplished by running `kubelet` in a cgroup namespace, and enabling `cgroupfs` driver for the cgroup hierarchy delegated by systemd.

To enable cgroup v2 resource limitation, `k3s server --rootless` needs to be launched as `systemctl --user` service.
Please see the comment lines in `k3s-rootless.service` for the usage.

Running `k3s server --rootless` via a terminal is not supported.
When it really needs to be launched via a terminal, `systemd-run --user -p Delegate --tty` needs to be prepended to create a systemd scope.
