 Description   

Collection validation with {background:true} much establish all the needed collection and index cursors on the current checkpoint. We cannot allow a new checkpoint to take place because then we might get some cursors on one checkpoint and some on another, and validation needs a single point-in-time view of the data.

This task is to add concurrency control for checkpoint requests such that the validation code can access it. SERVER-42223 will start using it.
