Add documentation about configuration options

[davsclaus]

We should have more docs for camel-quarkus. One page should be about general configuration where you can set many options on camel.main.xxx and for example also for components via camel.component.xxx=123 etc

We should add the page to the TOC
https://camel.apache.org/camel-quarkus/latest/user-guide.html

And also have another page for build time configurations, where you can use
quarkus.camel.xx to configure things.

The build time has the following options
https://github.com/apache/camel-quarkus/blob/master/extensions/core/runtime/src/main/java/org/apache/camel/quarkus/core/CamelConfig.java

IIRC the Quarkus project auto generate their configuration docs from the JavaDoc applied to ConfigItem annotated fields.

Maybe we should try to do something similar?

We now have Camel Quarkus specific options on extension pages. Camel options are listed on the respective component pages to which we link from extension pages. I think we can close this as done. If you feel there is still something to do, please file a new issue that reflects the current state.
