What this PR does / why we need it:
I recently runs into a problem with the query-frontend where the query wasn't the right result but the querier would return the right result.
Turns out this is due to querysharding, when doing sharding we actually insert missing 0 point when stepping on the results of each shards.
However this is wrong, zero during a min_over_time means something different, or even when dividing during a binary operations this can cause the creation of NaN.
The solution is simple we don't need to insert those points.
