Provide test for high-level use case: Create Camel project/modify Java file/start locally

[apupier]

should we create the test inside this repository or another one as it goes beyond just Camel LSP but general Camel development?

• create camel project:
  -- which possibility to test first? maybe use git clone on https://github.com/jboss-fuse/fuse-rest-http-booster
• modify Camel route Java file
  -- check classic java completion available
  -- check Camel completion available
• use springboot dashboard related command to start the project
