Disable the submodule fetch in a declarative way

[zioalex]

Summary

It would be great to have the possibility to disable the sub-modules feature in a declarative way.
Today it is only possible globally as documented here https://argoproj.github.io/argo-cd/user-guide/private-repositories/#git-submodules

Ideally it would part of the Declarative Setup as defined here https://argoproj.github.io/argo-cd/operator-manual/declarative-setup/

Motivation

We have a project that doesn't need to fetch all the sub-modules in all the stages.
So it would be great if we can control such config in a declarative way.

Proposal

The idea is to have a feature toggle directly in the repo declaration like:

apiVersion: argoproj.io/v1alpha1
kind: Application
metadata:
  name: guestbook
  namespace: argocd
spec:
  project: default
  source:
    repoURL: https://github.com/argoproj/argocd-example-apps.git
    targetRevision: HEAD
    path: guestbook
    fetch_submodules: false
  destination:
    server: https://kubernetes.default.svc
    namespace: guestbook

Is there a possibility of getting this in? I need to disable submodules for a single app, but don't want to disable globally and this is currently preventing me from using ArgoCD for this app.

We would like to utilize this feature as well.

Especially useful if you have repo pointing to github.com, and your argocd is in offline mode, because of security constraints. The deployment fail like;

 ComparisonError
rpc error: code = Internal desc = Failed to checkout 7a34387fdf439e8a8f9f126703b1f3da709aa0d6: `git submodule update --init --recursive` failed exit status 1: Cloning into '/tmp/https:__github.*******_cicd_*******'... fatal: unable to access 'https://github.com/.......

For everyone like me, who had no idea how to disable it globally,

kubectl set env deployment/argocd-repo-server ARGOCD_GIT_MODULES_ENABLED=false

Another voice of support here, pulling submodules is causing a lot of issues for me.

For the helm chart:

repoServer:
  env:
    - name: ARGOCD_GIT_MODULES_ENABLED
      value: "false"

I'd be in favor of a new field in the Application spec to disable submodules for a specific App.

Also trying to improve discoverability of the global config item: #10157

I really like the idea of having it the declarative way as described in the proposal. Maybe this should also be configurable per Project.

How to use command parameters in the cli command to disable it?
