issue: #35563 1. Use an internal health checker to monitor the cluster's health state, storing the latest state on the coordinator node. The CheckHealth request retrieves the cluster's health from this latest state on the proxy sides, which enhances cluster stability. 2. Each health check will assess all collections and channels, with detailed failure messages temporarily saved in the latest state. 3. Use CheckHealth request instead of the heavy GetMetrics request on the querynode and datanode Signed-off-by: jaime <yun.zhang@zilliz.com>
