1. Use goroutine pool instead of sem.
2. Remove compaction executor from pipeline, since in streaming mode
pipeline should be decoupled from compaction.

Iterators are long deprecated, but sort are still using it. This PR
unifies stats task with the latest compaction common functions and
remove the usage of iterators.
1. Rename `datanode/compaction` to `datanode/compactor`
2. Add `internal/compaction` and move some compaction commons into it.
3. Replace `DeltalogIterators` with `ComposeDeleteFromDeltalogs`
4. Remove `datanode/iterators`

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
