There is no parameter to disable argocd in installer

Argocd is just used for Continuous Deployments

This cmd is able to temporary delete argocd:
helm uninstall devops -n argocd

While restart installer pod, the argocd is installed again.

Now we support to use argocd in host cluster, not support to use argocd in member cluster.

Some users only have low resources in host cluster, so they do not want to launch jenkins in host cluster, only launch argocd in host cluster, while launch jenkins in member cluster.

We should support user to config whether launch jenkins or argocd.

Redesign DEVOPS format:

devops:
  enabled: false
  ci: 
    enabled: false
  cd: 
    enabled: false
    type: argocd/fluxcd
