Description

### Search before asking

- [x] I had searched in the [issues](https://github.com/apache/kvrocks/issues) and found no similar issues.

### Motivation

When creating a time series, the `[IGNORE ignoreMaxTimedestampDiff ignoreMaxValDiff]` options can be specified. During samples writing through `TS.ADD/TS.MADD`, samples meeting certain condition will be ignored.

Redis reference:
https://redis.io/docs/latest/commands/ts.create/

### Solution

- Add two fields(ignoreMaxTimedestampDiff ignoreMaxValDiff) to timeseries metadata
- When adding samples, determine whether the "ignore" condition is met.
- Add go integrated test

### Are you willing to submit a PR?
