- add redo interceptor to implement append context refresh. (make new
timetick)
- add create segment handler for flusher.
- make empty segment flushable and directly change it into dropped.
- add create segment message into wal when creating new growing segment.
- make the insert operation into following seq: createSegment -> insert
-> insert -> flushSegment.
- make manual flush into following seq: flushTs -> flushsegment ->
flushsegment -> manualflush.

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.

This pr will remove pre-marking segments as L2 during clustering
compaction in version 2.5, and ensure compatibility with version 2.4.
The core of this change is to **ensure that the many-to-many lineage
derivation logic is correct, making sure that both the parent and child
cannot simultaneously exist in the target segment view.**
feature:
- Clustering compaction no longer marks the input segments as L2.
- Add a new field `is_invisible` to `segmentInfo`, and mark segments
that have completed clustering but have not yet built indexes as
`is_invisible` to prevent them from being loaded prematurely."
- Do not mark the input segment as `Dropped` before the clustering
compaction is completed.
- After compaction fails, only the result segment needs to be marked as
Dropped.
compatibility:
- If the upgraded task has not failed, there are no compatibility
issues.
- If the status after the upgrade is `MetaSaved`, then skip the stats
task based on whether TmpSegments is empty.
- If the failure occurs before `MetaSaved`:
- there are no ResultSegments, and InputSegments have not been marked as
dropped yet.
- the level of input segments need to revert to LastLevel
- If the failure occurs after `MetaSaved`:
- ResultSegments have already been generated, and InputSegments have
been marked as Dropped. At this point, simply make the ResultSegments
visible.
- the level of ResultSegments needs to be set to L1（in order to
participate in mixCompaction）

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.

This PR add quota configuration for l0 segment entry number per
collection. If l0 compaction cannot keep up the insertion/upsertion
rate, this feature could back press the related rate.
