SERVER-55156 removes the capped collection truncation optimization here in an effort to simplify the work needed for SERVER-16049. Using a ranged truncation may prove useful for workloads where the insertion of one document requires the deletion of multiple documents.

A few things that we'd need to make this a reality that came to mind:

• Implement a new record store function to do ranged truncation on a collection.
  • Similiar to cappedTruncateAfter().
• Create a new oplog entry type for replicating these truncation operations.
