Make measures aggregation start & stop parameters mandatory

[Sergio Colinas]

When you do measures aggregation with needed_overlap 0 (it is our default), if you don't specify start and stop parameters sometimes the api omit results.

not sure if this matters to your use case, but you can backfill values so it doesn't omit results.

It is not clear which is the expected result when start and stop are not specified. I though all results should be included because not filter is applied but it was not the case.

[gordon chung (chungg)]

tbh, it's not obvious. i think this needs to be documented

based on code, the result is the last contiguous sequence where all series overlap. ie if

series1: __, __, __, __, 10, 20, __, 30, 40
series2: 10, 20, 30, 40, 50, 60, 70, 80, 90,

i believe the return value is only the last points. (do not quote me)

[Sergio Colinas (sergio-n)]

Thanks gordon! I still think that those parameters should be mandatory or if you use needed_overlap 0 it should return all the points. And yes, this needs to be documented.
