We want to support broadcast operation for both streaming and msgstream.
But msgstream can be only sent message from rootcoord and proxy.
So this pr move the streamingcoord to rootcoord to make easier
implementation.

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. Segments generated from inserts will be loaded as growing until they
are sorted by primary key.
2. This PR may increase memory pressure on the delegator, but we need to
test the performance of stats. In local testing, the speed of stats is
greater than the insert speed.

- Start channel manager on datacoord, but with empty assign policy in
streaming service.
- Make collection at dropping state can be recovered by flusher to make
sure that
milvus consume the dropCollection message.
- Add backoff for flusher lifetime.
- remove the proxy watcher from timetick at rootcoord in streaming
service.

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.
