GitOps (implemented in Argo CD) improvement

We only provided the basic function of the Argo CD to implement the GitOps feature. Those features are planned:

- [x] #694
- [x] #695
- [x] Support to edit the Argo CD application via UI (see https://github.com/kubesphere/ks-devops/issues/608)
- [ ] Support updating the images of Applications automatically (see https://github.com/kubesphere/ks-devops/issues/687)
* See also [the document](https://argocd-image-updater.readthedocs.io/)

There are some potential small features:
- [x] #696
* For example, the annotations belong to argocd

Annotations are used:
* `argocd-image-updater.argoproj.io/git-branch: main`
* `argocd-image-updater.argoproj.io/git-branch: base:target`
* `argocd-image-updater.argoproj.io/write-back-method: git:secret:argocd-image-updater/git-creds`
* `argocd-image-updater.argoproj.io/write-back-method: git`
* `argocd-image-updater.argoproj.io/write-back-target: kustomization`
* `argocd-image-updater.argoproj.io/.update-strategy: semver`
* `argocd-image-updater.argoproj.io/myimage.allow-tags: regexp:^[0-9a-f]{7}$`
* `argocd-image-updater.argoproj.io/api.pull-secret: pullsecret:argocd/osf2f-ghcr`

There are some potential issues that we might need to resolve:
