[3.6] Ensure the full logical session id is included in commands sent by the ShardingTaskExecutor

Some commands (including listCollections and listIndexes) forward the logical session id sent by the client. The client's logical session id will not include the information for the logged in user – the user information is collected from the operationContext on a mongos/mongod. If a command forwards the logical session id to a mongod without attaching the user information, the mongod will infer the system user instead of the logged in user.

This ticket will backport a section of SERVER-35323. With this section, the ShardingTaskExecutor will verify that the user information is included in any commands sent with a logical session id. The ShardingTaskExecutor will emplace the user information onto the command object if needed.
