    Round a duration in order to remove irrelevant information for duration which do not need to be accurate (usually when duration is formatted for the UI).
    As of current implementation, the following rules are applied
    - Seconds are removed for duration longer than 5 minutes.
    - Minutes are rounded for duration longer than 2 hours (to current hour if minutes are below 30, to next 1 hour if minutes above 30)
    - Minutes are removed for duration longer than a day
    - Hours are removed for duration longer than a week
    Examples :
```
 Util.formatDuration(Util.roundDuration(38000)); // 38 s
 => 38 s
 Util.formatDuration(Util.roundDuration(76000)); // 1 min 16 s
 => 1 min 16 s
 Util.formatDuration(Util.roundDuration(1564512)); // 26 min 4 s
 => 26 min
 Util.formatDuration(Util.roundDuration(5890000)); // 1 h 38 min 10 s
 => 1 h 38 min
 Util.formatDuration(Util.roundDuration(33165000)); // 9 h 12 min 45 s
 => 9 h
 Util.formatDuration(Util.roundDuration(35025000)); // 9 h 43 min 45 s
 => 10 h
 Util.formatDuration(Util.roundDuration(130993000)); // 1 day 12 h 23 min 13 s
 => 1 day 12 h
 Util.formatDuration(Util.roundDuration(236158000)); // 2 days 17 h 35 min 58 s
 => 2 days 18 h
 Util.formatDuration(Util.roundDuration(731675000)); // 8 days 11 h 14 min 35 s
 => 8 days
 Util.formatDuration(Util.roundDuration(5934547000L)); // 68 days 16 h 29 min 7 s
 => 68 days
 
```
