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.

See https://twitter.com/roidelapluie/status/1363428376162295811

The `last_over_time(m[d])` function already exists in MetricsQL.
