openyurt: [BUG] Cannot setup openyurt with `yurtctl convert --provider kind`

What happened: Hello, I’d like to deploy the openyurt cluster with yurtctl and kind. It seems that yurtctl supports kind with option --provider kind. However, when I used the following command, it resulted in error.

yurtctl convert -t --provider kind --cloud-nodes ${cloudnodes}

F0921 08:08:07.173618   12871 convert.go:98] fail to complete the convert option: failed to read file /etc/systemd/system/kubelet.service.d/10-kubeadm.conf, open /etc/systemd/system/kubelet.service.d/10-kubeadm.conf: no such file or directory

I read the code and found that when yurtctl starts, it will read the 10-kubeadm.conf (at /etc/systemd/system/kubelet.service.d/10-kubeadm.conf in default) to get pod manifest path. However, the file and directory does not exsit when using kind. Maybe we should come out a better way to solve it.

What you expected to happen: We can use yurtctl to deploy openyurt with kind.

How to reproduce it (as minimally and precisely as possible): Use yurtctl convert -t --provider kind --cloud-nodes ${cloudnodes} to deploy openyurt with kind.

Environment:

• OpenYurt version: commit: 797c43d
• Kubernetes version (use kubectl version): 1.20
