Enforce that no arguments can be passed to commands that do not use any

[mmotejlek]

Kubestr currently silently ignores unnecessary arguments that are passed to commands that do not use any. I have changed the behaviour to enforce that no arguments can be passed to these commands.

The reason is to prevent user errors that come from accidentally using unescaped space characters. In particular ( #105 ):
-N key=value, foo=bar
instead of
-N key=value,foo=bar
would be uncaught without this change.

Looks like the golangci-lint action failed because the setup-go action is trying to use go 1.19. Previous runs with go 1.18 worked. I will open another PR to pin the action to use go 1.18.

@mmotejlek can you rebase/merge your branch with master to get CI to pass? Thanks.
