Aliaksandr Valialkin 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.
