pre-allocating the logID and segmentID.

Due to the removal of injection and syncSegments from the compaction, we
need to ensure that no compaction is successfully executed during the
rolling upgrade. This PR renames Compaction to CompactionV2, with the
following effects:
- New datacoord + old datanode: Utilizes the CompactionV2 interface,
resulting in the datanode error "CompactionV2 not implemented," causing
compaction to fail;
- Old datacoord + new datanode: Utilizes the CompactionV1 interface,
resulting in the datanode error "CompactionV1 not implemented," causing
compaction to fail.

Feature Introduced:
1. Ensure ImportV2 waits for the index to be built
Enhancements Introduced:
1. Utilization of local time for timeout ts instead of allocating ts
from rootcoord.
3. Enhanced input file length check for binlog import.
4. Removal of duplicated manager in datanode.
5. Renaming of executor to scheduler in datanode.
6. Utilization of a thread pool in the scheduler in datanode.

This PR introduces novel managerial roles for importv2:
1. ImportMeta: To manage all the import tasks;
2. ImportScheduler: To process tasks and modify their states;
3. ImportChecker: To ascertain the completion of all tasks and instigate
relevant operations.

If DC restarted, those unkonwn compaction tasks
will never get call back in DN, so that the segments in the compaction
task will be locked, unable to sync and compaction again, blocking cp
advance and compaction executing.

This pr decoups importing segment from flush process by:
1. Exclude the importing segment from the flush policy, this approch
avoids notifying the datanode to flush the importing segment, which may
not exist.
2. When RootCoord call Flush, DataCoord directly set the importing
segment state to `Flushed`.

syncMgr.Block() will lock the segment when executing compaction.
Previous implementation was unable to Unblock thoese segments when
compaction failed. If next compaction of the same segments arrives,
it'll stuck forever and block all later compation tasks.
This PR makes sure compaction executor would Unblock these segments
after a failure compaction.
Apart form that, this PR also refines some logs and clean some codes of
compaction, compactor:
1. Log segment count instead of segmentIDs to avoid logging too many
segments
2. Flush RPC returns L1 segments only, skip L0 and L2
3. CompactionType is checked in `Compaction`, no need to check again
inside compactor
4. Use ligter method to replace `getSegmentMeta`
5. Log information for L0 compaction when encounters an error
