improve: chanage the `list` text format to normal list

[ericsyh]

Background

From https://github.com/streamnative/eng-support-tickets/issues/732, suggest changing the list text format to normal list like the kubectl output

kubectl get nodes
NAME                                STATUS   ROLES   AGE     VERSION
aks-agentpool-32271679-vmss000000   Ready    agent   5d19h   v1.27.3
aks-agentpool-32271679-vmss000002   Ready    agent   2d11h   v1.27.3

which will be better for integration with some scripts.
