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.

7c6d3981bf lib/uint64set: allow reusing bucket16 structs inside uint64set.Set via uint64set.Release method 
This reduces the load on memory allocator in Go runtime in production workload.

d5dddb0953 all: use %w instead of %s for wrapping errors in fmt.Errorf 
This will simplify examining the returned errors such as httpserver.ErrorWithStatusCode .
See https://blog.golang.org/go1.13-errors for details.

f3ec424e7d lib/uint64set: small code cleanup and perf tuning 
* Remember the last accessed bucket on Has() call.
* Inline fast paths inside Add() and Has() calls.
* Remove fragile code with maxUnsortedBuckets inside bucket32.

605d588ba6 lib/uint64set: reduce memory usage in Union, Intersect and Subtract methods 
Iterate items with newly added Set.ForEach method instead of allocating `[]uint64`
slice for all the items before the iteration.

ca259864e2 lib/storage: return back inmemory inverted index for recent hour 
Issues fixed:
- Slow startup times. Now the index is loaded from cache during start.
- High memory usage related to superflouos index copies every 10 seconds.

d888b21657 lib/storage: add inmemory inverted index for the last hour 
It should improve performance for `last N hours` dashboards with update intervals smaller than 1 hour.

b986516fbe lib/storage: create and use lib/uint64set instead of map[uint64]struct{} 
This should improve inverted index search performance for filters matching big number of time series,
since `lib/uint64set.Set` is faster than `map[uint64]struct{}` for both `Add` and `Has` calls.
See the corresponding benchmarks in `lib/uint64set`.
