[Feature] Can LB support consistent hashing?

[dandyhuang]

Supported implementations:

wrr : Weighted round robin (Kratos Client 内置默认算法)
p2c : Power of two choices
random : Random

@dandyhuang Would you describe some of your scenarios where you need a consistent hashing LB policy. This will give us a better understanding of the background and the motivation for implementing it.

@clement2026 You can understand it as distributing some of the user's redis data and cache to different machines.

Hi, @dandyhuang. I'm Dosu, and I'm helping the Kratos team manage their backlog. I'm marking this issue as stale.

Issue Summary:

• You requested the addition of a consistent hashing load balancing feature to the Kratos framework.
• The framework currently supports other algorithms like weighted round robin and random selection.
• @clement2026 asked for specific scenarios where consistent hashing is needed.
• You explained its usefulness for distributing user data and cache across machines, such as in a Redis setup.

Next Steps:

• Please let us know if this issue is still relevant to the latest version of the Kratos repository by commenting here.
• If there is no further activity, this issue will be automatically closed in 7 days.

Thank you for your understanding and contribution!
