// Determines when an upload should be scheduled. A domain's config will
// specify minimum and maximum upload delays; the minimum upload delay ensures
// that Chrome will not send too many upload requests to a site by waiting at
// least that long after the first beacon, while the maximum upload delay makes
// sure the server receives the reports while they are still fresh.
//
// When everything is working fine, the scheduler will return precisely that
// interval. If all uploaders have failed, then the beginning or ending points
// of the interval may be pushed later to accomodate the retry with exponential
// backoff.
//
// See dispatcher.h for an explanation of what happens with the scheduled
// interval.
