lib/logger/throttler.go: show the original location of the error and warning message
Previously the location inside LogThrottler implementation was shown. This could complicate debugging.

lib/blockcache: optimize blockcache a bit
- Optimize Cache.RemoveBlocksFromPart(), so it doesn't need to iterate over all the cached blocks.
- Cache blocks if there were no cache misses during the last 2 minutes.
  This may be the case when new blocks are added simultaneously to the storage and to the cache.

lib/{mergeset,storage}: properly limit cache sizes for indexdb
Previously these caches could exceed limits set via `-memory.allowedPercent` and/or `-memory.allowedBytes`,
since limits were set independently per each data part. If the number of data parts was big, then limits could be exceeded,
which could result to out of memory errors.

lib/promscrape: always initialize http client for stream parsing mode
Stream parsing mode can be automatically enabled when scraping targets with big response bodies
exceeding the -promscrape.minResponseSizeForStreamParse , so it must be always initialized.

lib/promscrape: store the full response in stream parsing mode in scrapeWork.lastScrape byte slice
This allows sending staleness marks and properly calculate scrape_series_added metric in stream parsing mode
at the cost of the increased memory usage, since now the potentially big response is kept
in the lastScrape byte slice per each scrapeWork.

In practice the memory usage increase shouldn't be big, since the response size
is usually much smaller than the parsed metrics from this response after the relabeling,
which usually adds a big pile of target-specific labels per each metric.

f3e89754a9 lib/promscrape: reduce CPU usage for common case when calculating scrape_series_added metric
Also reduce CPU usage when applying `series_limit` to scrape targets with constant set of metrics.

The main idea is to perform the calculations on scrape_series_added and series_limit
only if the set of metrics exposed by the target has been changed.
Scrape targets rarely change the set of exposed metrics,
so this optimization should reduce CPU usage in general case.

d5622b32e2 lib/promscrape: reduce memory and CPU usage when Prometheus staleness tracking is enabled for metrics from deleted / disappeared scrape targets
Store the scraped response body instead of storing the parsed and relabeld metrics.
This should reduce memory usage, since the response body takes less memory than the parsed and relabeled metrics.
This is especially true for Kubernetes service discovery, which adds many long labels for all the scraped metrics.

This should also reduce CPU usage, since the marshaling of the parsed
and relabeld metrics has been substituted by response body copying.
