Development support for VS Code Language Support for Apache Camel extension

Motivation

Camel 3 products, Camel Extensions for Quarkus, Camel for Spring Boot and Camel K include developer tools with community support only.

Red Hat cannot provide full “production” support for developer extensions on VSCode.

Customers need support for developer tools, at least to file customer tickets and get fixes in the latest versions under best effort SLA.

Goal

Add development support for VS Code Language Support for Apache Camel extension

Scenarios

As a developer I need to install a supported Language support extension to VSCode so that I get language assistance when writing integrations in DSLs (Java, XML, Camel K)

As a developer I need the language support for a specific Camel product version (Camel catalog version in Extension Settings, default latest, CEQ 2.7 -> Camel 3.14)

Expected outcomes

Continuous testing with productized Camel catalog

Manual configuration of Camel catalog version in Extension Settings because most of the time it is complicated to set it automatically (there are some parts for which the version cannot be specified currently - traits for Camel K for instance)
