Add TODO with link to design doc and indicate this is temporary

[sunjian, 2017/02/10 18:32:46]

I'm not sure what TODO to add. We can't get rid of this constructor until we
decide to implement PerformanceResourceTiming the same way
PerformanceNavigationTiming is implemented. I don't know if it is a separate bug
to fix.
