ReservedRuntimeEnvironmentVariables (aws-parent 3.2.3 API)

```
public interface ReservedRuntimeEnvironmentVariables
```
Lambda runtimes set several environment variables during initialization. Most of the environment variables provide information about the function or runtime. The keys for these environment variables are reserved and cannot be set in your function configuration.
