Support same repository address but different projects

[yyzxw]

Summary

similar to #9581 , support same repository address in different projects.

Motivation

we used ArgoCD as the backend engine for GitOps, and in a multi-tenant scenario, we isolated different projects as tenants. So we want different projects to save the same url, because even with the same url, their credentials may be different. or just distinguish by project.

Proposal

1. repo store

apiVersion: v1
kind: Secret
metadata:
  name: repo-83006512331
  labels:
    argocd.argoproj.io/secret-type: repository
data:
  name: repoName
  project: projectID
  type: git
  url: gitURL

why don't we use project and url as the key to create and query.

2. repo connection state

as mentioned above, the same URL may use different credentials, so also need to get the connection status of the repository for each project and url as the cache key.

3. repo credentials

apiVersion: v1
kind: Secret
metadata:
  name: argoproj-https-creds
  namespace: argocd
  labels:
    argocd.argoproj.io/secret-type: repo-creds
stringData:
  url: https://github.com/argoproj
  type: helm
  password: my-password
  username: my-username
  project: projectID     # add field

add project field. but there seems to be too much duplication with the repo definition. maybe it can be removed.

4. how implement?

• create
  use default project as default project if user not select project, is also for compatibility.
• query
  query repo list need add project as query param
• repo state
  repo cache key format:

  repo|repoURl|project|connection-state
  

  the cache needs to be rebuilt.

Or if there's any way to do that, please let me know. Thank you!

If this proposal is acceptable, I will submit a PR for it.

Hi, see #18290 - let me know what you think

Reopening since that was the spec that got merged, not the actual implementation :)
