maintainMs() in TimeWindows:

public long maintainMs() {

}
```
This code is indeed a bit complicated. I did some investigation and came to
the following results:
For 2.8 the retention times with default grace period are:
- `TimeWindows`:
- **24h** if window size is less than 24h,
- **window size** if window size is greater than or equal to 24h.
- `SessionWindows`:
- **24h** if the inactivity gap is less than 24h,
- **inactivity gap** if the inactivity gap is greater than or equal to 24h.
- `JoinWindows`:
- **24h** if window size is less than 24h,
- **window size** if window size is greater than or equal to 24h.
For 3.0 the retention times with default grace period are:
- `TimeWindows`:
- **window size + grace windows**
- `SessionWindows`:
- **inactivity gap + grace windows**
- `JoinWindows`:
- **window size + grace windows**
