Changes for ~~SERVER-34738~~ now display the lock requester's mode. We need to display the lock holder's mode as well.

We should change the following

            print("MongoDB Lock at {} ({}) held by {} waited on by {}".format(

                lock_head, lock_request["mode"], lock_holder, lock_waiter))

           # Code to set the lock_mode needs to be added

            print("MongoDB Lock at {} ({}) held by {} waited on by {} ({})".format(

                lock_head, lock_mode, lock_holder, lock_waiter, lock_request["mode"]))

Other references to lock_request["mode"] should be modified as well, such that the mode is properly associated to holder.
