lib/promscrape: expose promscrape_series_limit_max_series and promscrape_series_limit_current_series metrics per each scrape target with the enabled unique series limiter

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.

lib/promscrape: add -promscrape.minResponseSizeForStreamParse command-line option for automatic switching to stream parsing mode when scraping targets with big responses
...
This should reduce memory usage when vmagent scrapes targets with non-uniform response sizes.
This is common case in Kubernetes monitoring.
