Previously query shard locks the querylock in collectionReplica before any search/query The lock range is too large and easy to cause dead lock This PR makes following changes: - Rename collectionReplica to metaReplica which is more reasonable - Make release collection operation cancels waiting search/query request - Reduce the queryLock to collection level - Add some unit tests for timeout & released case Signed-off-by: NCongqi Xia <congqi.xia@zilliz.com>
