Issue Description:
Tracing is an important means of identifying bottleneck points in a
system and is crucial for debugging production issues. Milvus(or any DB)
is generally the most downstream system for an user call -- a user call
can originate from UI and pass through multiple components, in
micro-services architecture, before reaching Milvus.
So, when an user experiences a glitch, one would debug the call trace
via logs using a common trace id. As of now, Milvus generates a new
trace id for every call and this request is to make sure client can pass
the trace id which will be used for all the logs across the Milvus
sub-components so that one can fetch logs for a user call across the
components -- including Milvus.

This PR
1. Pass Materialized View (MV) search information obtained from the
expression parsing planning procedure to Knowhere. It only performs when
MV is enabled and the partition key is involved in the expression. The
search information includes:
1. Touched field_id and the count of related categories in the
expression. E.g., `color == red && color == blue` yields `field_id ->
2`.
2. Whether the expression only includes AND (&&) logical operator,
default `true`.
3. Whether the expression has NOT (!) operator, default `false`.
4. Store if turning on MV on the proxy to eliminate reading from
paramtable for every search request.
5. Renames to MV.
## Rebuttals
1. Did not write in `ExtractInfoPlanNodeVisitor` since the new scalar
framework was introduced and this part might be removed in the future.
2. Currently only interested in `==` and `in` expression, `string` data
type, anything else is a bonus.
3. Leave handling expressions like `F == A || F == A` for future works
of the optimizer.

2. Batch updates of multiple vchannel checkpoints are performed in the

the lock for channelCPs in DataCoord meta has been switched from key
lock to global lock.
