issue: #35821
After collection loaded, if we need to increase/decrease collection's
replica, we need to release and load it again.
milvus offers 4 solution to update loaded collection's replica, this PR
aims to dynamic change the replica number without release, and after
replica number changed, milvus will execute load replica or release
replica in async, and the replica loaded status can be checked by
getReplicas API.
Notice that if set too much replicas than querynode can afford，the new
replica won't be loaded successfully until enough querynode joins.

This PR introduce stats task for import:
1. Define new `Stats` and `IndexBuilding` states for importJob
2. Add new stats step to the import process: trigger the stats task and
wait for its completion
3. Abort stats task if import job failed

This issue only occurs for a short time right after a table is created.
To avoid this, we simply reduce the frequency of cleaning up invalid
limiter nodes.

This PR includes the following changes:
1. Added a new task type to the task scheduler in datacoord: stats task,
which sorts segments by primary key.
2. Implemented segment sorting in indexnode.
3. Added a new field `FieldStatsLog` to SegmentInfo to store token index
information.

issue: #34985#35493
after querynode has been suspended, it's not allow to load
segment/channel on it, which means the node is read only. to be
compatible with resource group design, after query node has been
suspend, we remove it from it's original resource group, make it a read
only query node in replica. then two things will happens:
1. it's original resource group will be lacking of query nodes, query
coord will assign new node to it.
2. querycoord will try to move out all segments/channels after querynode
has been suspended

* If a sparse vector with 0 non-zero value is inserted, no ANN search on
this sparse vector field will return it as a result. User may retrieve
this row via scalar query or ANN search on another vector field though.
* If the user uses an empty sparse vector as the query vector for a ANN
search, no neighbor will be returned.

Seals the largest growing segment if the total size of growing segments
of each shard exceeds the size threshold(default 4GB). Introducing this
policy can help keep the size of growing segments within a suitable
level, alleviating the pressure on the delegator.

issue: #34595
When consuming insert data on the delegator node, QueryCoord will move
out some sealed segments to manage its memory usage. After the growing
segment gets flushed, some sealed segments from other workers will be
moved back to the delegator node. To avoid the frequent movement of
segments, we estimate the maximum growing row count and preserve a
fixed-size memory in the delegator node.
