The sharding_ddl_util::removeCollAndChunksMetadataFromConfigremoveCollAndChunksMetadataFromConfig() helper method implements the removal of any sharding metadata concerning a collection and supports the commit of several DDL operations (such as dropCollection, dropDatabase, convertToCapped).

Due to historical reason, such an implementation is composed by 3 non-atomic steps, and this may potentially introduce undesired side effects in case the DDL doesn't adopt replay protection countermeasures.

This can be easily improved by converting removeCollAndChunksMetadataFromConfig() into a transaction.
