Description

Support for spring-boot configuration allows users to configure the component properties but does not give any hint on nested properties.

There are many components that declare properties on nested beans.
Eg. camel-docker has only one property named configuration . I found this pattern in components that allow users to specify a default value on the component and override it on each endpoint, if necessary.

Setting the property:

camel.component.docker.configuration.host=172.28.128.4

allows a user to specify the docker host, but the tooling does not give suggestions about that property.

A way to allow the users to view the nested properties is using the NestedConfigurationProperty annotation on the spring-boot configuration class. The spring-boot inspector will scan the nested class for properties.

The drawback is that the javadoc is not read from setters. Another drawback is that we will be using a different approach respect to the "read-the-json" one.

We need to figure out how to add these properties.
