Search before asking

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

Motivation

Refer: #2558
We should implement TDIGEST.MIN TDIGEST.MAX command.

Redis command reference:

• https://redis.io/docs/latest/commands/tdigest.min/
• https://redis.io/docs/latest/commands/tdigest.max/

Solution

Depends on #2791

We can follow the implementation of #2791 for this command.

To write more comprehensive integration tests, it will be better to be implemented after #2792 .
