This PR:
- Add `BufferedForward` to limit memory usage forwarding stream delete
- Add `UseLoad` flag to determine `Delete` shall use `segment.Delete` or
`segment.LoadDelta`
- Fix delegator accidentally use always true candidate while load
streaming delta

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

TSafe manager is too complex for current implementation and each
delegator need one goroutine waiting for tsafe update event.
Tsafe updating could be executed in pipeline. This PR remove tsafe
manager and simplify the entire logic of tsafe updating.

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.

milvus will add released segment to excluded info, and filter out it's
stream data in filter_node. but for data buffered in insert_node's
channel, if it belongs to growing segment which already be released,
then it will all the growing segment back again.
This PR maintain `excluded segments` in delegator, and check excluded
segment before new growing segment.

including proxy, data node to receive and write sparse float vectors to
binlog, query node to handle search requests, index node to build index
for sparse float column, etc.

When the TimeTravel functionality was previously removed, it
inadvertently affected the MVCC functionality within the system. This PR
aims to reintroduce the internal MVCC functionality as follows:
1. Add MvccTimestamp to the requests of Search/Query and the results of
Search internally.
2. When the delegator receives a Query/Search request and there is no
MVCC timestamp set in the request, set the delegator's current tsafe as
the MVCC timestamp of the request. If the request already has an MVCC
timestamp, do not modify it.
3. When the Proxy handles Search and triggers the second phase ReQuery,
divide the ReQuery into different shards and pass the MVCC timestamp to
the corresponding Query requests.

When Delegator processes delete data, it forwards delete data with only
segment id specified. When two segments has same segment id but one is
growing and the other is sealed, the delete will be applied to both
segments which causes delete data out of order when concurrent load
segment occurs.
