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.

47872ada7e app/vmselect/promql: do not ajdust offset value provided in the query 
Previously it could be modified in order to improve response cache hit ratio.
This is unneeded, since cache hit ratio should remain good because the query time range
should be already aligned to multiple of `step` values.
