A large number of wiredtiger statistics are only attached to the connection, which means when debugging a mongodb failure the https://docs.mongodb.com/manual/reference/command/collStats/ command won't assist in understanding the issue at a collection specific level. As such we should extend most if not all collection level statistics to be also at the data source level.

Work here:

• Review all connection level statistics that aren't already included in the data source statistics.

• Add all relevant ones to the data source.
