ArgoCD plugin support

[ewega]

Summary

Add ArgoCD as a supported DevOps tool in the CLI. ArgoCD is the leading GitOps/CD tool for Kubernetes, providing deployment frequency and change tracking data for DORA metrics.

Upstream Plugin

argocd in incubator-devlake/backend/plugins/argocd/

Property	Value
Plugin slug	argocd
Auth	AccessToken
Scope type	Applications (Name string in namespace)
Scope ID field	name
Default endpoint	User-provided ArgoCD server URL
Remote-scope API	Yes
Connection test	Yes

Dependencies

Blocked by:

• Generic scope ID extraction and remote-scope API client #86 — Scope ID extraction (needs ScopeIDField)

Not blocked by #85 — ArgoCD uses AccessToken, compatible with current auth model.

Changes

• Add ConnectionDef for argocd in connectionRegistry:
  • Endpoint: "" (user must provide)
  • SupportsTest: true
  • TokenPrompt: "ArgoCD auth token"
  • EnvVarNames: []string{"ARGOCD_TOKEN", "ARGOCD_AUTH_TOKEN"}
  • EnvFileKeys: []string{"ARGOCD_TOKEN", "ARGOCD_AUTH_TOKEN"}
  • ScopeIDField: "name"
  • ScopeFunc: scopeArgoCDHandler
• Implement scopeArgoCDHandler:
  • Use client.ListRemoteScopes("argocd", connID, "", "") to list applications
  • Let user select applications interactively
  • PUT selected applications as scopes
• Set Available: true

Acceptance Criteria

• gh devlake configure connection add --plugin argocd --endpoint https://argocd.example.com creates an ArgoCD connection
• ArgoCD appears in interactive plugin picker
• ArgoCD scopes list applications for selection
• Connection test works
• go build ./..., go test ./..., go vet ./... pass

@copilot Please implement ArgoCD plugin support now from latest main. Add a registry entry in cmd/connection_types.go, implement a registry-driven ScopeFunc using ListRemoteScopes/SearchRemoteScopes, avoid hardcoded plugin switches outside connectionRegistry, add tests, update README/docs, run go build ./..., go test ./..., and go vet ./..., and open a PR that closes #93.

Implemented and merged. ArgoCD is now a fully available plugin in the CLI.

Merged PR:

• PR Add ArgoCD plugin support #134 — Add ArgoCD plugin support: argocd ConnectionDef with Available: true, ScopeIDField: "name", scopeArgoCDHandler for listing/selecting applications via remote scopes, ArgoCDAppScope type in internal/devlake/types.go, tests, docs

All acceptance criteria satisfied: --plugin argocd connection creation with user-supplied endpoint, interactive plugin picker, application scope browsing, connection test, and CI gates pass.
