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.

0144b164c7 app/vmselect: add sign(q) and clamp(q, min, max) functions, which will be added in the upcoming Prometheus release 
See https://twitter.com/roidelapluie/status/1363428376162295811

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

3062ff0fdb app/vmselect: export per-tenant stats on the number of requests and the cumulative request duration 
The metrics are:
- vm_vmselect_http_requests_total{accountID="...",projectID="..."} - the total number of select requests per each tenant
- vm_vmselect_http_duration_ms_total{accountID="...",projectID="..."} - the total duration in milliseconds for per-tenant select requests

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.
