all: add -inmemoryDataFlushInterval command-line flag for controlling the frequency of saving in-memory data to disk
The main purpose of this command-line flag is to increase the lifetime of low-end flash storage
with the limited number of write operations it can perform. Such flash storage is usually
installed on Raspberry PI or similar appliances.

For example, `-inmemoryDataFlushInterval=1h` reduces the frequency of disk write operations
to up to once per hour if the ingested one-hour worth of data fits the limit for in-memory data.

The in-memory data is searchable in the same way as the data stored on disk.
VictoriaMetrics automatically flushes the in-memory data to disk on graceful shutdown via SIGINT signal.
The in-memory data is lost on unclean shutdown (hardware power loss, OOM crash, SIGKILL).

lib/storage: do not pass retentionMsecs and isReadOnly args explicitly - access them via Storage arg
This makes code easier to read.

lib/storage: stop background merge when storage enters read-only mode
This should prevent from `no space left on device` errors when VictoriaMetrics
under-estimates the additional disk space needed for background merge.

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.

fd41f070db lib/storage: sort tag filters by the number of loops they need for the execution
This metric should work better than the filter execution duration, since it cannot be distorted
by concurrently running queries.

d962568e93 all: use %w instead of %s for wrapping errors in fmt.Errorf
This will simplify examining the returned errors such as httpserver.ErrorWithStatusCode .

347aaba79d lib/{storage,mergeset}: use time.Ticker instead of time.Timer where appropriate
It has been appeared that time.Timer was used in places where time.Ticker must be used instead.
This could result in blocked goroutines as in the https://github.com/VictoriaMetrics/VictoriaMetrics/issues/316 .

de0e4eee2c 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`.
