Remaining issues with reconciliation
--------------------------------------------
Note that both before, and after this change, the command sometimes terminates
early, and does not wait for the service to reconcile; this is most apparent
when rolling back is scaling up (so more tasks are deployed);
$ docker service rollback foo
foo
service rolled back: rollback completed
$ docker service rollback foo
