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.

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

This PR also fixes bugs in l0 compactor where
l0 results would never be removed from datanode

This PR:
- Separates compaction scheduler and check results loop So that slow in
check-loop doesn't influence execution.
- Cleans compaction tasks when drop a vchannel so dropped-channel's
compaction tasks won't be checked over and over again.
- Skips meta change when meta's already changed, avoid panic
- Remove not inuse injectDone(bool) parameter

Compaction plan result contained one segment for one plan. For l0
compaction would write to multiple segments, this PR expand the segments
number in plan results and refactor some names for readibility.
- Name refactory: - CompactionStateResult -> CompactionPlanResult -
CompactionResult -> CompactionSegment
