cli: docker service|node|stack ps instead of tasks

Browse source 
Rather than conflict with the unexposed task model, change the names of
the object-oriented task display to `docker <object> ps`. The command
works identically to `docker service tasks`. This change is superficial.

This provides a more sensical docker experience while not trampling on
the task model that may be introduced as a top-level command at a later
date.

The following is an example of the display using `docker service ps`
with a service named `condescending_cori`:

```
$ docker service ps condescending_cori
ID                         NAME                  SERVICE             IMAGE   LAST STATE              DESIRED STATE  NODE
e2cd9vqb62qjk38lw65uoffd2  condescending_cori.1  condescending_cori  alpine  Running 13 minutes ago  Running        6c6d232a5d0e
```

The following shows the output for the node on which the command is
running:

```console
$ docker node ps self
ID                         NAME                  SERVICE             IMAGE   LAST STATE              DESIRED STATE  NODE
