ae91a6883c lib/{storage,mergeset}: clean cached index blocks and inmemory blocks more aggressively 
Previously such blocks were cleaned after they weren't accessed during 10 minutes.
Now they are cleaned after one minute of missing access. This should reduce memory usage in general case.

add short_version label to vm_app_version metric (#877) 
* add short_version label to vm_app_version metric

use case:  Version panel of Grafana dashboard should use a live query, but currently it uses a template query which becomes stale.  Grafana is not able to preform regex substitution on labels.

71ea4935de 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.

764dc2499f 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`).

Previously the maximum cache lifetime has been limited by 10 seconds. Now it is extended up to a day.
This should reduce CPU usage in the following cases:

* when querying recently added data with small churn rate for time series
* when querying historical data
