Using the environment variable here also has the advantage that it can be copied and pasted directly in a terminal and it will work.

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

this brings back the trailing whitespace in "runmetrics",
that were there intentially to force a line-break
also removes a duplicate redirect, that was present

Swarm mode makes it possible through the API to set labels to containers
but not through command line. This tries to fix it.

Instead reserve exit code 2 to be future proof, document that it should
not be used. Implementation-wise, it is considered as unhealthy, but
users should not rely on this as it may change in the future.
