lib/promscrape/discovery/kubernetes: use unsupportedFieldError() function instead of errContext string 
This improves code readability and maintainability a bit, since the format string
is passed as string literal into fmt.Errorf.

all: follow-up after 8edb390e21 
- Remove unused js bloatware from /targets page. This strips down binary size by more than 100Kb
- Add /service-discovery page for API compatibility with Prometheus
- Properly load bootstrap.min.css from /prometheus/targets
- Serve static contents for /targets page from app/vminsert instead of app/vmselect, because /targets page is served from there

Consul SD - update services on the watcher's start (#2202) 
* lib/discovery/consul: update services on the watcher's start

Previously, watcher's start was only initing goroutines for discovery
but not waiting for the first iteration to end. It means first Consul
discovery wasn't returning discovered targets until the next iteration.

The change makes the watcher's start blocking until we get first discovery
iteration done and all registries updated.

app/{vmalert,vmagent}: improve the distribution of scrape offsets among targets / rules 
Previously only the lower part of 64-bit hash was used for calculating the offset.
This may give uneven distribution in some cases. So let's use all the available 64 bits from the hash
for calculating the offset.

lib/promscrape: do not populate response body to memory in stream parsing mode if -promscrape.noStaleMarkers is set 
The response body isn't used if -promscrape.noStaleMarkers is set after the commit 2876137c92 ,
so there is no sense in pupulating it in memory. This should reduce memory usage when scraping big responses.

lib/promscrape: do not sort original labels and do not intern label string for the original labels before the sharding code is executed 
This should reduce CPU and memory usage in shard mode when service discovery finds big number of scrape targets with many long labels.

lib/promscrape: reduce memory usage if -promscrape.noStaleMarkers command-line flag is passed 
Do not store in memory the response from the last scrape per each target if -promscrape.noStaleMarkers option is enabled.
This should reduce memory usage when the scraped targets return large responses.

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.
