Fix/kind pod backup with command

[poyaz]

Summary

• When creating API with pod kind in k8s, then can't make a backup with command because the pod doesn't have OwnerReferences and when the code gets a list of pods the code panicked

Other changes

I added a test for checking to get a list of pods to make a backup. Also, I found a problem in the helm chart of the minio, The URL https://helm.min.io/ was not found and I changed it to https://charts.min.io/. The value of the chart has been changed and I have to change e2e/definitions/minio/helm.yaml according to these values.
