Kubelet doesn't support subcommands and silently ignores them.
This causes a lot of confusion among users, for example:
Running 'kubelet logs' can produce this output:
I0206 16:20:40.010949 5712 feature_gate.go:220] feature gates: &{{} map[]}
I0206 16:20:40.011054 5712 controller.go:114] kubelet config controller: starting controller
...
error: failed to run Kubelet: failed to create kubelet:
misconfiguration: kubelet cgroup driver: "cgroupfs" is different from
docker cgroup driver: "systemd"
The output in this case looks like a valid log output. The error is not
caused by incorrectly configured cgroup driver though. It's caused by
the fact that kubelet ignores 'logs' subcommand, so 'kubelet logs' is
essentially the same as 'kubelet': it runs kubelet with the default set
of parameters, including default cgroup driver.
Added check to prevent kubelet from running if user specifies
subcommands in the command line.
Fixes: #639
