Implement first iteration of Rest DSL

[lordrip]

Please describe the feature that you want to propose

Context

Currently, the Camel YAML schema is available in the zustand store at useSchemasStore

Despite that, there's no Rest Configuration UI available yet.

Goal

The goal is to provide a first iteration of the config UI for Rest and RestConfiguration objects.

Requirements (can be implemented in subsequent GitHub issues if needed)

1. Create a dedicated Rest page that will hold the Rest-related UI
2. Provide a simple mechanism to create new Rest and RestConfiguration objects. Please see the POC

3. Upon clicking one of the objects, the AutoForm component should be fired with the model and the schema and connect it through a callback to update the model.

We also need an import functionality which takes an openAPI spec file and generates the Rest / Routes parts for the user.

Lowering the priority as it might be enough to provide just the OpenAPI import ( API First ) in the first iteration.

We are moving the OpenAPI import to the VS Code extension. Rest DSL will not be part of the feature parity milestone. I am moving this issue back to the backlog.
