Fixing and testing BITCOUNT with negative start/stop.

This patch:
1. Add a `BitmapString::NormalizeRange` for handling the range
2. For BITCOUNT/BITPOS, fixing the syntax of `value.size()`
3. Add the testing

The current encoding design:
```
search data type metadata:

key (index name) -> flag | expire | version | size | on_data_type (HASH or JSON)

prefixes encoding:

key (index name) | PREFIXES -> prefix1 prefix2 ...

tag field metadata encoding:

key (index name) | TAG_FIELD_META | field name -> separator | case sensitive

tag field index encoding:

key (index name) | TAG_FIELD | field name | tag | key -> (nil)
```

This PR implemented the cluster slot migration by the rocksdb write batch,
which will bring performance benefits. Also, we don't need to depend on
parsing commands from the write batch log data if enabled. This makes the
cluster migration feature more robust since we don't have to take care
of the log data in each write batch.

This closes #2008

…tion (#2103)

We expired a key with 1 second which is too short for testing the expiration time,
because `Metadata::ExpireMsToS` function will use rounding to get a closer time value if
METADATA_64BIT_ENCODING_MASK was disabled.

This closes #2091

This is a refactor, see: #2076

Previously, adhoc bit operations are used. This patch extract `GetBit` and `SetBitTo` operation to simplify the impl.

Also, because the LSB/MSB format we're using it different in BitmapString and Bitmap( see apache/kvrocks-website#198 ), `lsb` and `msb` is extracted to prevent from mistakes.

Just a small corrections of spelling in config file:
- rites changes to writes
- Removed describing a compression level because we use
  a hardcode compress_level and no config options for her
