05672ffc32 app/vmselect/promql: properly handle (a op b) default N if (a op b) returns NaN series 
The result should be a series with `N` values and `a op b` labels. Previously such series has been removed from the result.

ca75432e66 app/vmselect: do not track queries with less than 1ms execution time at /api/v1/status/top_queries 
This should improve the readability and usefullness of the /api/v1/status/top_queries when debugging slow queries
or queries that take too much cpu time.

4ba3fd9e6d lib/workingsetcache: switch from split cache to full cache after the cache size exceeds 95% of split capacity 
Previously the switch occurred when the cache size becomes 100% of its capacity. The cache size could never reach 100% capacity.
This could prevent from switching from the split cache to full cache, thus reducing the cache effectiveness.

a925d5a3e1 app/vmselect/promql: duration handling improvements in MetricsQL queries 
- Support durations anywhere in MetricsQL queries. E.g. sum_over_time(m[1h])/1h is equivalent to sum_over_time(m[1h])/3600
- Support durations without suffix. E.g. rate(m[300]) is equivalent to rate(m[5m])

8ca2799478 lib/storage: properly determine when the deduplication is needed in needsDedup 
Previously needsDedup() could return true if the de-duplication wasn't needed for the following case:

         d < interval
           /     \
   |        v | v        |
     interval   interval

Now it properly returns false for this case

a7694092b8 Revert "lib/uint64set: allow reusing bucket16 structs inside uint64set.Set via uint64set.Release method" 
This reverts commit 7c6d3981bf.

Reason for revert: high contention at bucket16Pool on systems with big number of CPU cores.
This slows down query processing significantly.

8aa9bba9bd lib/{mergeset,storage}: switch from sync.Pool to chan-based pool for inmemoryPart objects 
This should reduce memory usage on systems with big number of CPU cores,
since every inmemoryPart object occupies at least 64KB of memory and sync.Pool maintains
a separate pool inmemoryPart objects per each CPU core.

Though the new scheme for the pool worsens per-cpu cache locality, this should be amortized
by big sizes of inmemoryPart objects.

78c9174682 lib/mergeset: increase pool capacity for inmemoryBlock according to collected profiles from production workload 
CPU and memory profiles show that the pool capacity for inmemoryBlock objects is too small.
This results in the increased load on memory allocation code in Go runtime.
Increase the pool capacity in order to reduce the load on Go runtime.

f71e4d1853 lib/mergeset: limit the frequency for flushCallback calls to once per 10 seconds 
This should improve hit ratio for tagFiltersCache when big number of new time series are constantly registered
(aka high churn rate). This, in turn, should reduce CPU usage for queries over such time series.

0020b9f904 lib/workingsetcache: properly update stats for requests and cache misses 
Previously the stats for cache misses could be improperly counted, because it had inflated cache misses
if the entry was missing in the curr cache, but was existing in the prev cache.

The same applies to cache requests - they were inflated if the entry was missing in the curr cache.
