Support for custom section (tags)

[angelozerr]

We should support https://quarkus.io/guides/qute-reference#user_tags

With qute you can write custom section like

{#user inject:user img=true size=20/}

see https://github.com/FroMage/quarkus-renarde-todo/blob/5384be6c070d11e5aff200f2469d969c100af088/src/main/resources/templates/main.html#L23

This user name comes from the src/main/resources/templates/tags/user.html name file.

In other words all Qute template which are stored inside src/main/resources/templates/tags folder are considered as a section.

quarkus-renarde provides tags too and when this project is on the classpath, it provides the capability to use them in the user project.

For instance the quarkus project quarkus-renarde-todo use #form

{#form uri:Todos.done(todo.id) klass="inline"}

see https://github.com/FroMage/quarkus-renarde-todo/blob/5384be6c070d11e5aff200f2469d969c100af088/src/main/resources/templates/Todos/index.html#L24

which comes from the template of the referenced quarkus-renarde with

src/main/resources/templates/tags/form.html

I discover this logic in:

• https://github.com/quarkusio/quarkus/blob/28ee52cfdac44c4985ac49433ce8525c49b899d2/extensions/qute/runtime/src/main/java/io/quarkus/qute/runtime/EngineProducer.java#L75 which initialize the src/main/resources/templates/tags
• https://github.com/quarkusio/quarkus/blob/28ee52cfdac44c4985ac49433ce8525c49b899d2/extensions/qute/runtime/src/main/java/io/quarkus/qute/runtime/EngineProducer.java#L173 which loop for template id coming from the src/main/resources/templates/tags
