issue: #33744
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.

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.

and resource groups. then when load collections will use the load

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.

To speed up the construction and querying of Bloom filters, we chose a
blocked Bloom filter instead of a basic Bloom filter implementation.
WARN: This PR is compatible with old version bf impl, but if fall back
to old milvus version, it may causes bloom filter deserialize failed.
In single Bloom filter test cases with a capacity of 1,000,000 and a
false positive rate (FPR) of 0.001, the blocked Bloom filter is 5 times
faster than the basic Bloom filter in both querying and construction, at
the cost of a 30% increase in memory usage.
- Block BF construct time {"time": "54.128131ms"}
- Block BF size {"size": 3021578}
- Block BF Test cost {"time": "55.407352ms"}
- Basic BF construct time {"time": "210.262183ms"}
- Basic BF size {"size": 2396308}
- Basic BF Test cost {"time": "192.596229ms"}
In multi Bloom filter test cases with a capacity of 100,000, an FPR of
0.001, and 100 Bloom filters, we reuse the primary key locations for all
Bloom filters to avoid repeated hash computations. As a result, the
blocked Bloom filter is also 5 times faster than the basic Bloom filter
in querying.

This PR introduce two database level props:
1. database.replica.number
2. database.resource_groups
User can set those two database props by AlterDatabase API, then can
load collection without specified replica_num and resource groups. then
it will use database level load param when try to load collections.

Before executing the import, partition IDs should be reordered according
to partition names. Otherwise, the data might be hashed to the wrong
partition during import. This PR corrects this error.
