e1a6262302 lib/fs: replace fs.OpenReaderAt with fs.MustOpenReaderAt
All the callers for fs.OpenReaderAt expect that the file will be opened.
So it is better to log fatal error inside fs.MustOpenReaderAt instead of leaving this to the caller.

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.

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`).

10f2eedee0 lib/storage: imrpove cache effectiveness for time series ids matching the given filters
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

82973f8ae7 Revert "lib/storage: remove unused fetchData arg from BlockRef.MustReadBlock"
This reverts commit bab6a15ae0.

Reason for revert: the `fetchData` arg is used in cluster branch.
Leaving this arg in master branch makes smaller the diff with cluster branch.
