Metrics in question:

• insertsApplied
• updatesApplied
• deletesApplied

1. Create functions to handle incrementation of the metrics (onInsertApplied, onUpdateApplied, onDeleteApplied)
2. Integrated external functions into the appropriate places where the operations are applied
3. Evaluate creating unit test for each helper function (onInsertApplied, onUpdateApplied, onDeleteApplied)

Not Included
This work does not include the persistence & restoration of the crudOp metrics. That'll be done by SERVER-63623
