Adjust execution limits for new job types.

Set new execution limits for user-initiated and data transfer jobs.
To start, we'll have the following execution limits:
* User-initiated: [10 minutes, 60 minutes]
* Data transfer: [10 minutes, 30 minutes] (same as regular jobs)
* User-initiated data transfer:
    [max{10 minutes, 1.35 * estimated transfer time}, 292471 millenia)

Also fix a bug in the estimated transfer time calculation.
