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

1. Add API to access task runtime metrics, including:
- build index task
- compaction task
- import task
- balance (including load/release of segments/channels and some leader
tasks on querycoord)
- sync task
2. Add a debug model to the webpage by using debug=true or debug=false
in the URL query parameters to enable or disable debug mode.

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.

This PR includes the following adjustments:
1. To prevent channelCP update task backlog, only one task with the same
vchannel is retained in the updater. Additionally, the lastUpdateTime is
refreshed after the flowgraph submits the update task, rather than in
the callBack function.
2. Batch updates of multiple vchannel checkpoints are performed in the
UpdateChannelCheckpoint RPC (default batch size is 128). Additionally,
the lock for channelCPs in DataCoord meta has been switched from key
lock to global lock.
3. The concurrency of UpdateChannelCheckpoint RPCs in the datanode has
been reduced from 1000 to 10.

This pr decoups importing segment from flush process by:
1. Exclude the importing segment from the flush policy, this approch
avoids notifying the datanode to flush the importing segment, which may
not exist.
2. When RootCoord call Flush, DataCoord directly set the importing
segment state to `Flushed`.
