public @interface RuntimeStart
```
Run time of the application (as opposed to build time).
This is from the point of view of ahead of time compilation, such as when using GraalVM native-image.
There are two phases of an application lifecycle:
- BuildTimeStart - Application should not connect anywhere, this is to initialize the environment before native-image is generated. Configuration available is build-time specific and MUST not be used for runtime operation of this application
- Runtime (this annotation) - Application is starting and should set up all resources. Configuration available at runtime is intended for runtime of this application
Example of usage in a CDI Extension:
```
 void initRuntime(@Observes @RuntimeStart io.helidon.config.Config config) {}
 
```
End of runtime is equivalent to end of ApplicationScoped, so there is no need to create additional annotations.
