After SERVER-81359, in replica set endpoint mode, the client will see only the shard-role suboperations that result from the router role self-routing the client's original commands. For example, a client that sends "drop" will subsequently see "_shardsvrDropCommand" and no "drop". This is likely to result in confusion for users that expect to see commands in a fashion that resembles traditional replica sets.

Change the behavior of currentOp to return operations across both roles when in replica set endpoint mode. Additionally, add a field to currentOp output that announces the role that each operation belongs to.
