Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/891

This commit also adds `"isPartial":{true|false}` field to `/api/v1/*` responses. `"isPartial":true` is set when the response
is based on a partial data because some of vmstorage nodes weren't available during query processing.

Now `/targets` endpoint accepts optional `show_original_labels=1` query arg, which shows original labels for each target.
This may simplify debugging for target relabeling.

This function works with both Prometheus-style and VictoriaMetrics-style buckets.
The function removes buckets with the lowest values in order to reserve the highest precision.
The function is useful for building heatmaps in Grafana from too big number of buckets.

0bff96fe4b lib/storage: prioritize data ingestion over heavy queries 
Heavy queries could result in the lack of CPU resources for processing the current data ingestion stream.
Prevent this by delaying queries' execution until free resources are available for data ingestion.

Expose `vm_search_delays_total` metric, which may be used in for alerting when there is no enough CPU resources
for data ingestion and/or for executing heavy queries.
