17d08c1fe0 app/vmselect: adjust end arg instead of adjusting start arg if start > end 
`start` arg has higher chances to be set properly comparing to `end` arg,
so it is expected that the `end` arg could be adjusted if it was set incorrectly.

6ca4b94511 lib/storage: increase the number of created time series in BenchmarkHeadPostingForMatchers in order to be on par with Promethues 
The previous commit was accidentally creating 10x smaller number of time series than Prometheus
and this led to invalid benchmark results.

The updated benchmark results:

6f61fd367a lib/storage: add BenchmarkHeadPostingForMatchers similar to the benchmark from Prometheus 
See the corresponding benchmark in Prometheus - 23c0299d85/tsdb/head_bench_test.go (L52)

The benchmark allows performing apples-to-apples comparison of time series search
in Prometheus and VictoriaMetrics. The following article - https://www.robustperception.io/evaluating-performance-and-correctness -
contains incorrect numbers for VictoriaMetrics, since there wasn't this benchmark yet. Fix it.

Benchmarks can be repeated with the following commands from Prometheus and VictoriaMetrics source code roots:

- Prometheus: GOMAXPROCS=1 go test ./tsdb/ -run=111 -bench=BenchmarkHeadPostingForMatchers
- VictoriaMetrics: GOMAXPROCS=1 go test ./lib/storage/ -run=111 -bench=BenchmarkHeadPostingForMatchers

The first column (old) is for Prometheus, the second column (new) is for VictoriaMetrics.

Prometheus was using 3.5GB of RAM during the benchmark, while VictoriaMetrics was using 400MB of RAM.

494ad0fdb3 lib/storage: remove inmemory index for recent hour, since it uses too much memory 
Production workload shows that the index requires ~4Kb of RAM per active time series.
This is too much for high number of active time series, so let's delete this index.

Now the queries should fall back to the index for the current day instead of the index
for the recent hour. The query performance for the current day index should be good enough
given the 100M rows/sec scan speed per CPU core.
