lib/storage: deduplicate samples more thoroughly
...
Previously some duplicate samples may be left on disk for time series with high churn rate.
This may result in higher disk space usage.

lib/storage: remove prioritizing of merging small parts over merging big parts, since it doesn't work as expected
...
The prioritizing could lead to big merge starvation, which could end up in too big number of parts that must be merged into big parts.
Multiple big merges may be initiated after the migration from v1.39.0 or v1.39.1. It is OK - these merges should be finished soon,
which should return CPU and disk IO usage to normal levels.

all: use %w instead of %s for wrapping errors in fmt.Errorf
...
This will simplify examining the returned errors such as httpserver.ErrorWithStatusCode .
See https://blog.golang.org/go1.13-errors for details.

lib/storage: create and use lib/uint64set
instead of map[uint64]struct{}
...
This should improve inverted index search performance for filters matching big number of time series,
since `lib/uint64set.Set` is faster than `map[uint64]struct{}` for both `Add` and `Has` calls.
See the corresponding benchmarks in `lib/uint64set`.
