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).

4. Removal of duplicated manager in datanode.
5. Renaming of executor to scheduler in datanode.

during FilterIndexedSegment in GetRecoveryInfo, it try to acquire index
meta's read lock for every segment. when a collection has thousands of
segments, which may blocked for more than 10 seconds and even longer.
cause `AddSegmentIndex` may also triggered frequently, which try to get
the write lock.
This PR avoid acquire index meta's lock for each segment
