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.

app/vmselect/promql: adjust memory limits calculations for incremental aggregate functions
...
Incremental aggregate functions don't keep all the selected time series in memory -
they keep only up to GOMAXPROCS time series for incremental aggregations.
Take into account that the number of time series in RAM can be higher if they are split
into many groups with `by (...)` or `without (...)` modifiers.
This should reduce the number of `not enough memory for processing ... data points` false
positive errors.

and big
directories
...
Certain partition directories may be missing after restoring from backups
if they had no data. Re-create such directories on start.

lib/storage: substitute error message about unsorted items in the index block after metricIDs merge with counter
...
The origin of the error has been detected and documented in the code,
so it is enough to export a counter for such errors at `vm_index_blocks_with_metric_ids_incorrect_order_total`,
so it could be monitored and alerted on high error rates.
Export also the counter for processed index blocks with metricIDs - `vm_index_blocks_with_metric_ids_processed_total`,
so its' rate could be compared to `rate(vm_index_blocks_with_metric_ids_incorrect_order_total)`.

lib/storage: separate the max inverted index scan loops per metric into fast and slow loops
...
Slow loops could require seeks and expensive regexp matching, while fast loops just scans
all the metricIDs for the given `tag=value` prefix. So these operations must have separate
max loops multiplier.

lib/storage: try potentially faster tag filters at first, then apply slower tag filters
...
The fastest tag filters are non-negative non-regexp, since they are the most specific.
The slowest tag filters are negative regexp, since they require scanning
all the entries for the given label.
