1. Provide partition&channel level indexing in the collection target.
2. Make `SegmentAction` not wait for distribution.
3. Remove scheduler and target manager mutex.
4. Optimize logging to reduce CPU overhead.

before querycoord stop gracefully, we will save the current target to
meta store and recover it after querycoord start up, to speed the
querycoord's recovery time. but the target version hasn't been recovered
as expected, and it use latest timestamp as current target's version,
which has no effect to querycoord but an unnecessary syncTargetVersion
func call.
This PR recover the correct target version to avoid unnecessary
syncTargetVersion func call

`LoadPartitions` does not guarantee the current target has loading
partitions if there are some partitions already loaded before.
This PR check current target contains the partition to load when
advancing loading percentage to 100.

issue: #28491
after querycoord restart, it will pull a new target, which include
channel and segment list. when segments loaded on querynode has reached
the target, the collection could provide search/query. but if segment
list changes by time, ater querycoord pull a new target, it will takes a
few minutes to catch up the target's segment distribution. and before
that, query/search will fail due to lack of segments.
This PR save the current loaded target to meta storein querycoord's stop
progress, and recover it when query coord starts, to speed up the target
recovery time.
