Support for Active/Active replication

### Search before asking

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

### Motivation

This is a feature, only available in the enterprise version of redis. Would like to request for this to be made possible in kvrocks......

kvrocks at most can only be set as an Active-Passive deployment, it makes it difficult to implement an Active-Active setup for disaster recovery purposes. The deram is to set up a Multi Active-Active kvrocks deployment, so we can achieve an Active Active Production and Disaster Recovery setup.

### Solution

Redis Enterprise
keyDB
and other sync tools like redis-shake

### Are you willing to submit a PR?

- [ ] I'm willing to submit a PR!

Start by mapping Kvrocks' existing active-passive replication and comparing the requested multi-active behavior with Redis Enterprise, KeyDB, and redis-shake. No files or tests are named, so locate the replication implementation and its tests first. Done should be a defined and tested active-active deployment supporting the stated production and disaster-recovery use case.
