0d44e371f3 lib/promscrape: add -promscrape.suppressDuplicateScrapeTargetErrors command-line flag in order to suppress duplicate scrape target errors 
Show also original labels for duplicate targets in error message in order to simplify debugging the issue.

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.

fd7dd5064a lib/storage: code cleanup after 10f2eedee0 
Remove the code that uses metricIDs caches for the current and the previous hour during metricIDs search,
since this code became unused after implementing per-day inverted index almost a year ago.

While at it, fix a bug, which could prevent from finding time series with names containing dots (aka Graphite-like names
such as `foo.bar.baz`).

Aliaksandr Valialkin
eee6f1e56d lib/persistentqueue: make the persistent queue more durable against unclean shutdown (kill -9, OOM, hard reset) 
The strategy is:

- Periodical flushing of inmemory blocks to files, so they aren't lost on unclean shutdown.
- Periodical syncing of metadata for persisted queues, so the metadata remains in sync with the persisted data.
- Automatic adjusting of too big chunk size when opening the queue. The chunk size may be bigger than the writer offset after unclean shutdown.
- Skipping of broken chunk file if it cannot be read.
- Fsyncing finalized chunk files.

34ef10fbcc lib/flagutil: avoid int overflow for arch 386 (#710) 
Arch 386 is a 32-bit architecture and interprets int type for numbers as an explicit int32,
whereas on most modern CPUs int is implicitly an int64. This makes tests to fail with
`int overflow` error.

9a77ae9d1c lib/promscrape: reduce memory usage when scraping targets with big number of metrics alongside targets with small number of labels 
Previously targets with big number of metrics and/or labels could generated too big buffers,
which then could be re-used when scraping targets with small number of metrics.
This resulted in memory waste.

Now big buffers are used only for targets with big number of metrics / labels,
while small buffers are used for targets with small number of metrics / labels.

4b89da9463 lib/decimal: rename significant decimal digits to significant figures (#698) 
The previous notion was inconsistent with what `decimal.Round` does.
According to [wiki](https://en.wikipedia.org/wiki/Significant_figures) rounding
applied to all significant figures, not just decimal ones.
