How about adding another class like ConfigGroup?
```
public static final ConfigGroup WEB_FRONTEND = new
ConfigGroup("WebFrontend",
WEB_BACKPRESSURE_DELAY,
WEB_BACKPRESSURE_NUM_SAMPLES
...
);
```
Unfortunately then we would need to add every option to a group. We could
add a testCase that will check if every option belongs to some ConfigGroup.
Also we could provide a helper annotation `@ConfigGroup(String name)` for
classes that all options belong to single ConfigGroup.
