create k8s pod network delay failed

Issue Description

one error occured in my expriment which is pod network delay expriment, the response is as below
{"code":504,"success":false,"error":"unexpected status, the real value is Error","result":{"uid":"ccd735769e4b0b40","success":false,"error":"unexpected status, the real value is Error","statuses":[{"uid":"eda98894-0f52-11ea-bee3-fa163e37e213","name":"chaosblade-tool-mwbw8","state":"Error","kind":"pod","error":"Error response from daemon: Get https://registry.cn-hangzhou.aliyuncs.com/v2/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)","success":false,"nodeName":"192.168.0.22"}]}}

then i check the log of operator, the command is as below
/opt/chaosblade/blade create docker network delay --time=3000 --remote-port=8231 --interface=cbr0 --container-id 0f8971f3fff67e95d6a7ab9b9153744fd0e59864b1c33ab82060d32d26d98248}]"

so i guess that the default image-repo is be used, but the pod exception does not support to assign the image-repo like docker expriment

Describe what you expected to happen

how can i resolove the problem?

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

Tell us your environment

chaosblade 0.4.0

Anything else we need to know?

1. my machine cannot access the domain of "registry.cn-hangzhou.aliyuncs.com"

2. command: ./blade create k8s pod-network delay --namespace XXXX --interface cbr0 --remote-port 8231 --labels app=XXX --evict-count 1 --time 3000 --kubeconfig ~/.kube/config

3. the used image of chaosblade-operator and chaosblade-tool is in my own image-repo
