Combining `-add` and `-rm` flags on `docker service update` should
be usable to explicitly replace existing options. The current order
of processing did not allow this, causing the `-rm` flag to remove
properties that were specified in `-add`. This behavior was inconsistent
with (for example) `--host-add` and `--host-rm`.
This patch updates the behavior to first remove properties, then
add new properties.
Note that there's still some improvements to make, to make the removal
more granulas (e.g. to make `--label-rm label=some-value` only remove
the label if value matches `some-value`); these changes are left for
a follow-up.

When doing `docker service inspect --pretty` on services without
`TaskTemplate.Resources` or `TaskTemplate.Resources.Limits`, the command
fails. This is due to a missing check on ResourceLimitPids().

Previously, if a registry AuthInfo was not present in the CLI config file, docker logout could not be used
to ask the credential helper to forget about it. It causes problem for people working with
multiple alternative config files, and it causes problems for cases like Docker Desktop w/ WSL 2, as
it uses the same win32 credential helper as the Windows CLI, but a different config file, leading to
bugs where I cannot logout from a registry from wsl2 if I logged in from Windows and vice-versa.

This adds the currently selected "docker context" to the output

}

After reloading the `~/.bashrc`, the prompt now shows the currently selected
`docker context`:
```bash

* Added two new modes accepted by the `--mode` flag
* `replicated-job` creates a replicated job
* `global-job` creates a global job.
* When using `replicated-job` mode, the `replicas` flag sets the
`TotalCompletions` parameter of the job. This is the total number of
tasks that will run
* Added a new flag, `max-concurrent`, for use with `replicated-job`
mode. This flag sets the `MaxConcurrent` parameter of the job, which
is the maximum number of replicas the job will run simultaneously.
* When using `replicated-job` or `global-job` mode, using any of the
update parameter flags will result in an error, as jobs cannot be
updated in the traditional sense.
* Updated the `docker service ls` UI to include the completion status
(completed vs total tasks) if the service is a job.
* Updated the progress bars UI for service creation and update to
support jobs. For jobs, there is displayed a bar covering the overall
progress of the job (the number of tasks completed over the total
number of tasks to complete).
* Added documentation explaining the use of the new flags, and of jobs
in general.

- Perform feature detection when actually needed, instead of during
initializing
- Version negotiation is performed either when making an API request,
or when (e.g.) running `docker help` (to hide unsupported features)
- Use a 2 second timeout when 'pinging' the daemon; this should be
sufficient for most cases, and when feature detection failed, the
daemon will still perform validation (and produce an error if needed)
- context.WithTimeout doesn't currently work with ssh connections (connhelper),
so we're only applying this timeout for tcp:// connections, otherwise
keep the old behavior.

When printing services' tasks with `docker service ps` command, tasks are grouped only by task slot.
This leads to interleaving tasks from different services when `docker service ps` is called with multiple services.
Besides this, global services do not have slots at all and printing tasks for them doesn't group and
doesn't properly indent tasks with \_.
With this patch all tasks are grouped by service ID, slot and node ID (relevant only for global services) and it fixes issue 533.

The `docker push` command up until [v0.9.1](https://github.com/moby/moby/blob/v0.9.1/api/client.go#L998)
always pushed all tags of a given image, so `docker push foo/bar` would push (e.g.)
all of `foo/bar:latest`, `foo:/bar:v1`, `foo/bar:v1.0.0`.
Pushing all tags of an image was not desirable in many case, so docker v0.10.0
enhanced `docker push` to optionally specify a tag to push (`docker push foo/bar:v1`)
(see https://github.com/moby/moby/issues/3411 and the pull request that implemented
this: https://github.com/moby/moby/pull/4948).
This behavior exists up until today, and is confusing, because unlike other commands,
`docker push` does not default to use the `:latest` tag when omitted, but instead
makes it push "all tags of the image"
For example, in the following situation;
```
docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
thajeztah/myimage latest b534869c81f0 41 hours ago 1.22MB
```
Running `docker push thajeztah/myimage` seemingly does the expected behavior (it
pushes `thajeztah/myimage:latest` to Docker Hub), however, it does not so for the
reason expected (`:latest` being the default tag), but because `:latest` happens
to be the only tag present for the `thajeztah/myimage` image.
If another tag exists for the image:
```
docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
thajeztah/myimage latest b534869c81f0 41 hours ago 1.22MB
thajeztah/myimage v1.0.0 b534869c81f0 41 hours ago 1.22MB
```
Running the same command (`docker push thajeztah/myimage`) will push _both_ images
to Docker Hub.
> Note that the behavior described above is currently not (clearly) documented;
> the `docker push` reference documentation (https://docs.docker.com/engine/reference/commandline/push/)
does not mention that omitting the tag will push all tags
This patch changes the default behavior, and if no tag is specified, `:latest` is
assumed. To push _all_ tags, a new flag (`-a` / `--all-tags`) is added, similar
to the flag that's present on `docker pull`.
With this change:
- `docker push myname/myimage` will be the equivalent of `docker push myname/myimage:latest`
- to push all images, the user needs to set a flag (`--all-tags`), so `docker push --all-tags myname/myimage:latest`
