    Description

      applyOps commands can include things like $inc operators that make them non-idempotent. Since applyOps entries get put in the oplog unchanged, non-idempotent applyOps commands can lead to non-idempotent oplog entries which is problematic. We do not create any bad applyOps entries internally, but external ones are allowed. We should check applyOps commands before running them and error on non-idempotent operations.
