 Description   

In order to support the opening of a changestream over a whole cluster, the ShardingCatalogClient needs to provide a new method for querying the relevant content stored in config.placementHistory.

Following the lead of SERVER-68929, the signature of the new method should be:

ListOfShards getShardsThatOwnDataAtClusterTime(dbName, clusterTime);
