Unless we are adding or removing environment variables, their order
shouldn't be changed. This makes it look like the service's TaskSpec has
changed relative to the old version of the service, and containers need
to be redeployed.
The existing code always rebuilds the list of environment variables by
converting them to a map and back, but there's no reason to do this if
no environment variables are being added.

This commit adds a hidden placeholder of `.Self` for
`docker node ls --format` so that if the node is the same
as the current docker daemon, then a `*` is outputed.

This fix tries to address the comment https://github.com/docker/docker/pull/30376#discussion_r97465334
where it was not possible to specify `--format` for `docker node ls`. The `--format` flag
is a quite useful flag that could be used in many places such as completion.
This fix implements `--format` for `docker node ls` and add `nodesFormat` in config.json
so that it is possible to specify the output when `docker node ls` is invoked.
Related documentations have been updated.
A set of unit tests have been added.
This fix is related to #30376.

Refactored the API to more easily accept new endpoints. Added REST,
client, and CLI endpoints for getting logs from a specific task. All
that is needed after this commit to enable arbitrary service log
selectors is a REST endpoint and handler.
Task logs can be retrieved by putting in a task ID at the CLI instead of
a service ID.

This fix is related to 30232 wherw `docker service ls`
does not show `PORTS` information like `docker service ps`.
This fix adds `PORTS` fields for services that publish
ports in ingress mode.
Additional unit tests cases have been updated.

Change "service create" and "service update" to wait until the creation
or update finishes, when --detach=false is specified. Show progress bars
for the overall operation and for each individual task (when there are a
small enough number of tasks), unless "-q" / "--quiet" is specified.

Currently these fields are included in the response JSON with zero
values. It's better not to include them if the information is
unavailable (for example, on a worker node).
This turns Cluster into a pointer so that it can be left out.

"docker node ps" behaves strangely outside swarm mode:
$ docker node ps
ID NAME IMAGE NODE DESIRED STATE CURRENT STATE ERROR PORTS
Error: No such node:
It should explain that the node is not a swarm manager.
The reason this happens is that the argument to "docker node ps" defaults
to "self". The first thing the command does is try to resolve "self" to
a node ID using the /info endpoint. If there is no node ID, it tries to
use the empty string as an ID, and tries to GET /nodes/, which is not a
valid endpoint.
Change the command to check if the node ID is present in the /info
response. If it isn't, a swarm API endpoint can supply a useful error
message.
Also, avoid printing the column headers if the only following text is an
error.
