--------------------------------------
Thanks [~curino], I cherry-picked it back to branch-2 cleanly.

> Duration of a reservation (endTime - startTime) is specified independently of
> the recurrence. This can lead to requests where the duration exceeds the
> periodicity, for e.g: an hourly reservation that runs for 2 hours. This will
> result in multiple concurrently active instances for the same reservation
> which is hard both to manage as well as grok. This jira proposes to reject
> such requests by clearly informing the user.
