/**
 * Indicates that a given class can be injected as a configuration object. A configuration group can contain multiple
 * nested items and configuration groups.
 * 
 * Configuration group properties cannot be {@code Optional} or {@code null}. It is expected that, in the event
 * that a group property can be disabled, this should be done using a {@code boolean} property (preferably the unnamed
 * property or a {@code enabled} property). For example:
 *
 * 
 * 
quarkus.extra-fast-mode         = yes
quarkus.extra-fast-mode.gadgets = 20

 * 
 *
 * Or:
 *
 *  * 
quarkus.laser-beam.enabled    = true
quarkus.laser-beam.mount-mode = sharks
 
 *
