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`.

c9063ece66 lib/storage: share tsids across all the partSearch instances 
This should reduce memory usage when big number of time series matches the given query.

0dc0006f34 lib/storage: calculate the maximum number of rows per small part from -memory.allowedPercent 
Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/159

This simplifies error detection additionally to the `vm_rows_ignored_total` counters.

09fc6e22e5 all: use workingsetcache instead of fastcache 
This should reduce the amount of RAM required for processing time series
with non-zero churn rate.

The previous cache behavior can be restored with `-cache.oldBehavior` command-line flag.

b8bb74ffc6 app/vmstorage: add vm_concurrent_addrows_* metrics for tracking concurrency for Storage.AddRows calls 
Track also the number of dropped rows due to the exceeded timeout
on concurrency limit for Storage.AddRows. This number is tracked in `vm_concurrent_addrows_dropped_rows_total`

f586e1f83c lib/storage: add metrics for calculating skipped rows outside the retention 
The metrics are:

    - vm_too_big_timestamp_rows_total
    - vm_too_small_timestamp_rows_total

d2c801029b lib/storage: persist metric ids for the current and the previous hour on graceful shutdown 
This should improve performance after restart when the db contains a lot of time series
with high time series churn (i.e. metrics from Kubernetes with many pods and frequent deployments)

28f6c36ab4 lib/storage: tune updating a map with today`s metric ids 
- Increase update iterval from 1s to 10s. This should reduce CPU usage
  for large amounts of metric ids with constant churn.
- Reduce pendingTodayMetricIDsLock lock duration during the update.
