Memory limits on connections

Search before asking

• I had searched in the issues and found no similar issues.

Motivation

The lack of memory constraints in current Kvrocks can lead to OOM, especially when deployed in container environments.

Solution

We should provide mechanisms to limit memory and avoid OOM.

In the connection dimension:

• avoid large WriteBatch
• limit connection output buffer, support client-output-buffer-limit and maxmemory-clients
