issue: #43828
Implement robust rewatch mechanism to handle etcd connection failures
and node reconnection scenarios in DataCoord and QueryCoord, along with
heartbeat lag monitoring capabilities.
Changes include:
- Implement rewatchDataNodes/rewatchQueryNodes callbacks for etcd
reconnection scenarios
- Add idempotent rewatchNodes method to handle etcd session recovery
gracefully
- Add QueryCoordLastHeartbeatTimeStamp metric for monitoring node
heartbeat lag
- Clean up heartbeat metrics when nodes go down to prevent metric leaks

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

issue: #34553
when rootcoord trigger graceful stop progress, it will block until all
rpc finished. for create collection request, rootcoord need to block
until datacoord finish to watch all channels, but datacoord need to call
`rootcoord.Alloc` during watch channel, and rootcoord doesn't respond to
new request anymore. which cause create collection stucks, and graceful
stop progress stucks.
This PR remove the func call `rootcoord.Alloc` to solve the logic dead
lock during graceful stop progress.
