add sparse float vector support to different milvus components,
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.

1. The Import APIs now provide detailed progress information for each
imported file, including details such as file name, file size, progress,
and more.
2. The APIs now return the collection name and the completion time.
3. Other modifications include changing jobID to jobId and other similar
adjustments.

cause balance channel will stuck until leader view catch up the current
target, then start to unsub the old delegator. which make sure that the
new delegator can provide search before release old delegator. but
another logic in segment_checker skip loading segment during balance
channel. so during balance channel, if query node crash, new delegator
can't catch up target forever, then stuck forever.
This PR remove the rule that skip loading segment during balance channel
to avoid the logic dead lock here.

This PR adds the ability to search/get sparse float vectors in segcore,
and added unit tests by modifying lots of existing tests into
parameterized ones.

cause balancer call wrong interface to get segment/channel list in
replica, then got a wrong average segment/channel number, which make
each node have less segment/channel than average, and the balance won't
be trigger in multi replica case.
This PR fix that balance segment/channel won't be trigger on multi

This commit adds sparse float vector support to segcore with the
following:
1. data type enum declarations
2. Adds corresponding data structures for handling sparse float vectors
in various scenarios, including:
* FieldData as a bridge between the binlog and the in memory data
structures
* mmap::Column as the in memory representation of a sparse float vector
column of a sealed segment;
* ConcurrentVector as the in memory representation of a sparse float
vector of a growing segment which supports inserts.
3. Adds logic in payload reader/writer to serialize/deserialize from/to
binlog
4. Adds the ability to allow the index node to build sparse float vector
index
5. Adds the ability to allow the query node to build growing index for
growing segment and temp index for sealed segment without index built
This commit also includes some code cleanness, comment improvement, and
some unit tests for sparse vector.

segment, it will try to correct leader view. but the sync action doesn't
specify the latest load version. so the update operation will failed.

This PR includes the following adjustments:
1. To prevent channelCP update task backlog, only one task with the same
vchannel is retained in the updater. Additionally, the lastUpdateTime is
refreshed after the flowgraph submits the update task, rather than in
the callBack function.
2. Batch updates of multiple vchannel checkpoints are performed in the
UpdateChannelCheckpoint RPC (default batch size is 128). Additionally,
the lock for channelCPs in DataCoord meta has been switched from key
lock to global lock.
3. The concurrency of UpdateChannelCheckpoint RPCs in the datanode has
been reduced from 1000 to 10.
