Update fedora_manual_config.md

removal of 
  # Add your own!
  KUBELET_ARGS=""
this line causes line with args in it to be over writen

removal of flag "--require-kubeconfig" as it prevents the service from starting with error "F0708 18:41:17.411350   11725 server.go:145] unknown flag: --require-kubeconfig"

this is with v1.10.1
