lib/blockcache: eliminate possible race when Cache.Put is called for the same entry from multiple goroutines
The race could result in incorrect cache size tracking, which, in turn, could result in too frequent cache cleaning

lib/blockcache: increase the lifetime for rarely accessed blocks from 2 minutes to 5 minutes
This should improve data ingestion speed if time series samples are ingested with interval bigger than 2 minutes.
The actual interval could exceed 2 minutes if the original interval between samples doesn't exceed 2 minutes
in the case of slow inserts. Slow inserts may appear in the following cases:

* Big number of new time series are pushed to VictoriaMetrics, so they couldn't be registered in 2 minutes.
* MetricName->tsid cache reset on indexdb rotation or due to unclean shutdown.
  In this case VictoriaMetrics needs to load MetricName->tsid entries for all the incoming series from IndexDB.
  IndexDB uses the block cache for increasing lookup performance. If the cache has no the needed block,
  then IndexDB reads and unpacks the block from disk. This requires an extra disk read IO and CPU.
  See https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1401

Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2007

This also should increase performance for periodically executed queries with intervals from 2 minutes to 5 minutes.
See the previous similar commit - 43103be011

It is possible that the timeout can be increased further. Let's collect production numbers for this change
so the timeout could be adjusted further.

lib/workingsetcache: use the original cache size limits when rotating caches
Previously limits for new caches were taken from cache stats.
These limits could mismatch the original limits. This could result in failed cache load
if the stored cache has been created with the limits obtained from cache stats.
