lib/storage: code cleanup after 10f2eedee0
...
Remove the code that uses metricIDs caches for the current and the previous hour during metricIDs search,
since this code became unused after implementing per-day inverted index almost a year ago.
While at it, fix a bug, which could prevent from finding time series with names containing dots (aka Graphite-like names
such as `foo.bar.baz`).

lib/storage: remove prioritizing of merging small parts over merging big parts, since it doesn't work as expected
...
The prioritizing could lead to big merge starvation, which could end up in too big number of parts that must be merged into big parts.
Multiple big merges may be initiated after the migration from v1.39.0 or v1.39.1. It is OK - these merges should be finished soon,
which should return CPU and disk IO usage to normal levels.

for data ingestion and/or for executing heavy queries.

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.
