This PR:
- Add `lock.RWMutex` & `lock.Mutex` alias to switch implementation based
on build flags
- When build flags has `test` in it, use `go-deadlock` to detect
possible deadlocks
- Replace all `sync.RWMutex` & `sync.Mutex` in datacoord pkg

1. nodeid based channel store access should use map access instead of
iteration.
2. The join-ish functions calls are slow when # collections/segments
increases (e.g. 10k).
e.g.
getNumRowsOfCollectionUnsafe is O(num_segments); GetAllCollectionNumRows
is of O(num_collections*num_segments).

This pr add more metrics, which are:
- Slow query count, which the duration considered as slow can be
configurable;
- Number of deleted entities;
- Number of entities imported;
- Number of entities per collection;
- Number of loaded entities per collection;
- Number of indexed entities;
- Number of indexed entities, per collection, per index and whether it's
a vetor index;
- Quota states (LongTimeTickDelay, MemoryExhuasted, DiskQuotaExhuasted)
per database;

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.

Previously the `SelectSegments` changed to clone all return value
preventing possible update to returned info.
Since meta is implemented following COW rules, this shall not happen and
any update on segment shall have copy before it.
This PR:
- Remove clone for read-only Get segment info
- Add Segment Operator abstraction for changing segment
- Implemnt COW for updating MaxRowNum

Compaction would copy logPaths from comapctFrom segA to compactTo segB,
and previous code would copy the logPath directly, causing there're
full-logPaths-of-segA in compactTo segB's meta. So, for the next
compaction of segB, if segA has been GCed, Download would report error
"The sperified key not found".
This PR makes sure compactTo segment's meta contains logID only. And
this PR also refines CompleteComapctionMutation, increasing some
readability and merge two methods into one.
