TODO - [ ] more general internal code implement

TODO: - [x] value_file support local and remote - [x] support default config for destination - [ ] use `goclient` instead of kubectl

If we want to change core config or var config definition, we have to change all docs. I think maybe we can define `core`, `var`, and `tool` config in one...

TODO - [ ] support init group and user in config - [ ] support default configs - [ ] high available docs

we have finished this func in repo-scaffolding, you can refer to this [doc](https://github.com/devstream-io/devstream/blob/main/docs/plugins/repo-scaffolding.md).

TODO - [ ] doc is not clear on how to get token - [ ] config is not consistent with other plugins

The rest of the plugins not using installer - [x] gitlabci - [x] jenkins - [x] jenkinspipelinekubernetes - [x] trello - [ ] trellogithub

what if filename template， for example golang reposcaffolding use _app_name_ for filename placeholder

look like argocd has go sdk, i will try to finish this. [doc](https://pkg.go.dev/github.com/argoproj/argo-cd/pkg/apiclient)

https://github.com/devstream-io/devstream/pull/1148 has add jenkinsfile pipeline for this issue
