🚀 Feature Description and Motivation

Currently, the gateway plugin doesn't support leader election, which means all instances are active simultaneously.

This can lead to:

• Inconsistent KV cache event processing across multiple instances
• Potential race conditions when handling shared resources
• No high availability with failover capabilities

Use Case

high availability with failover capabilities

Proposed Solution

Implement leader election support to enable an active-passive (leader-follower) architecture where only one instance is active at a time while others remain in standby mode.
