The config.placementHistory collection contains a log of namespace placement changes observed on the cluster over time, which change stream readers have to consult through a dedicated interface.

SERVER-68929 originally introduced 3 methods to the ShardingCatalogClient as the API to allow the consumption of such content from any mongod/s node. These methods are nevertheless of scarse utility, considering that:

• they act as mere passthrough methods for a dedicated config server method (introduced by SERVER-72872) which runs the business logic for querying config.placementHistory and ensuring proper serialization between read and reset requests of the log
• their signature does not match the current needs of V2 change stream readers.

The objective of this ticket is to:

• Remove the existing interface from ShardingCatalogClient
• Migrate from ShardingCatalogClientImpl to ShardingCatalogManager the aggregation logic to retrieve historical placement metadata.
• Have the command handler directly invoke the ShardingCatalogManager.
