e38ca28d99 app/vmselect/promql: increase accuracy for buckets_limit() function for small limits by skipping the first and the last buckets during merge 
The first and the last buckets are usually `[0 ... leMin]` and `(leMax ... +Inf)`. If they are merged with adjancent buckets,
then the resulting accuracy can suffer.

functions, which don't change the meaning of the time series shouldn't drop metric name.

478d8f8393 app/vmselect/promql: add count_le_over_time(m[d], le) and count_gt_over_time(m[d], gt) functions 
These functions returns the number of raw samples that don't exceed `le` or are bigger than `gt`.
These functions are complement to already existing `share_le_over_time(m[d], le)` and `share_gt_over_time(m[d], gt)`.
