ConfigConfig (Quarkus - Core - Runtime 3.6.3 API)

```
@ConfigMapping(prefix="quarkus")
@ConfigRoot(phase=RUN_TIME)
public interface ConfigConfig
```
We don't really use this, because these are configurations for the config itself, so it causes a chicken / egg problem, but we need it for documentation purposes.
Relocation of the Config configurations to the Quarkus namespace is done in ConfigUtils.configBuilder(boolean, io.quarkus.runtime.LaunchMode).

- Method Detail
  - profile
```
Optional<String> profile()
```
    Profile that will be active when Quarkus launches.
  - profileParent
```
@WithName("config.profile.parent")
Optional<String> profileParent()
```
    Accepts a single configuration profile name. If a configuration property cannot be found in the current active profile, the config performs the same lookup in the profile set by this configuration.
  - locations
```
@WithName("config.locations")
Optional<List<URI>> locations()
```
    Additional config locations to be loaded with the Config. The configuration support multiple locations separated by a comma and each must represent a valid URI.
  - mappingValidateUnknown
```
@WithName("config.mapping.validate-unknown")
Optional<Boolean> mappingValidateUnknown()
```
    Validates that a @ConfigMapping maps every available configuration name contained in the mapping prefix.
  - logValues
```
@WithName("config.log.values")
Optional<Boolean> logValues()
```
    Enable logging of configuration values lookup in DEBUG log level.
    The log of configuration values require the category set to DEBUG in the io.smallrye.config category: quarkus.log.category."io.smallrye.config".level=DEBUG.
  - uuid
```
Optional<String> uuid()
```
    A property that allows accessing a generated UUID. It generates that UUID at startup time. So it changes between two starts including in dev mode.
    Access this generated UUID using expressions: `${quarkus.uuid}`.
