[EPIC] Introduce the notion of app presets to ease generating Quarkus apps

[ia3andy]

Description

The goals of presets are:

• Make the growing list of Quarkus extensions easier to digest in the tooling (code.quarkus.io, CLI, ...)
• Speed up the process of creating specific apps (rest, cli, messaging, ...)

They would define a group of extensions (plus maybe some app settings) to be selected during app creation, or to be added on existing apps.

Fixes #16275

Call them recipes :) You want to bake a chocolate cake with vanilla frosting, you order that and the next day a box arrives at your door with the recipe and all the required ingredients pre-measured for you :)

In the future, it would also be interesting to see a config option for users to create their own combinations.

recipes implies steps - thus albeit I like the name these are just providing the ingredients to make the cake :)

For Event driven with Kafka https://code.quarkus.io/?e=messaging-kafka would be enough.

[cescoffier]

Yes, for Kafka, Ozan's link is enough.
