Delete pod in command line failed. ERROR: unknown flag: --labels

Issue Description

Type: feature request

Describe what happened (or what feature you want)

I want to delete the pod in command line, but it failed and get error: unknown flag: --labels

[root@k8s-master chaosblade-0.4.0]# ./blade create k8s pod-pod delete --labels app=ts-station-mysql --namespace default --evict-count 1 --kubeconfig /etc/kubernetes/admin.conf 
unknown flag: --labels

But I executed it successfully in yaml configuration file.

[root@k8s-master chaos-test]# kubectl apply -f delete-pod.yaml 
chaosblade.chaosblade.io/delete-two-pod-by-labels created
[root@k8s-master chaos-test]# 
[root@k8s-master chaos-test]# kubectl get pods
NAME                                READY   STATUS    RESTARTS   AGE
ts-station-mysql-58975db444-d2hj9   1/1     Running   0          7s

BTW, in the version 0.4.0-alpha, I can not get the help information in the deep command level, such as:

[root@k8s-master chaosblade-0.4.0]# ./blade create k8s -h
Create a chaos engineering experiment

I can only get the info "Create a chaos engineering experiment". Even if i execute a create command:

[root@k8s-master chaosblade-0.4.0]# ./blade create cpu load
Create a chaos engineering experiment
[root@k8s-master chaosblade-0.4.0]# ./blade create cpu load --cpu-count 2
unknown flag: --cpu-count

So I dont know how to create experiment in version 0.0.4-alpha. Since there are many changes in architecture of the tool in version 0.0.4-alpha, so is the deployment of the tool changed? I have deployed the chaosclade-operator and chaosblade-tool and built the choasblade-cli. Can you give me some suggestions guys, thanks!

Describe what you expected to happen

Create the experiments in command line and more docs info of the version 0.0.4-alpha.

How to reproduce it (as minimally and precisely as possible)

1. build the choasblade-cli in make.
2. execute command in the command line to get error info:

./blade create k8s pod-pod delete --labels app=ts-station-mysql --namespace default --evict-count 1 --kubeconfig /etc/kubernetes/admin.conf

3. execute command with k8s deployment yaml file to get successful result.
