Review Comment:
Just my two cents, in general, such an approach might be a problem. Let's
consider a simple test:
```
public class Test {
@WithSystemProperty(key = COLOCATION_FEATURE_FLAG, value = "false")
public vois testPartitionPerTable() {...}
@WithSystemProperty(key = COLOCATION_FEATURE_FLAG, value = "true")
public vois testPartitionPerZone() {...}
}
```
In that case, the value of
`DEFAULT_ZONE_DEFAULT_AUTO_ADJUST_SCALE_UP_TIMEOUT_SECONDS` will depend on the
test order.
