[Feature] [GSOC] IDE(editor) Plugins for editing OAM applications

[Somefive]

Is your feature request related to a problem? Please describe.

With more and more developers start writing KubeVela (OAM) application YAML file and CUE-based X-Definitions, it is increasingly important to provide some tools to help user make correct configurations. IDE plugin is one way to reach that. We can make VSCode/Jetbrains plugins for formatting and previewing the written applications.

Describe the solution you'd like

The plugin is expected to be able to:

1. Connect to the remote Kubernetes APIServer (KubeVela Control Plane) in the background and recognize the X-Definitions (ComponentDefinitions, TraitDefinitions, PolicyDefinitions, WorkflowStepDefinitions).
2. Highlight the type of components, traits, policies & workflowsteps in the application configuration.
3. Preview the rendering result (dryrun) of the components & traits.
4. Compare the difference between the current application configuration and the corresponding one on the remote cluster.
5. Preview the selected clusters by the topology policy.
6. For ComponentDefinition & TraitDefinition, provide validation for the CUE input and preview for the rendering result.

Describe alternatives you've considered

An alternative choice is to make some standalone development tools like desktop apps. It can be developed with cross-platform build tools like electron/dart.

Additional context

Feel free to discuss what this tool should be look like below. :)

This project is really awesome, and maybe there's a lot of interaction detail to discuss. I think the kernel is Watching some events and then calling a shell to execute kubectl or vela and do some string resolve.

But I'm new to kubevela, the first step is to get familiar with kubevela, then design the UI and interaction, right? could you give me some advice? @Somefive thx:)

@Charlie17Li Hi, glad to hear that. Let's leave this issue for the discussion of the IDE plugins. If you need advices on starting with KubeVela, you can contact me in the DingDing group or Slack channel.

Yes, for the IDE part, I think executing kubectl or vela could be one way to deal with that.
