[FEATURE REQUEST]: displayDuration for suite

[anujavk]

Feature request

Current behavior
Currently there is option to show displayDuration for specs and summary only

Wanted behavior
Additional option in suite to show displayDuration for each suite

What is the motivation / use case for changing the behavior?
It's a good feature to have if there has too many specs inside a suite and there are also multiple suites then displayDuration for suite will make the report better to understand.

@bcaudan if you think it makes sense to have this feature then I can implement this task in a new branch and create a pull request. I'm keen on doing it.
