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.
Before this change:
-----------------------------
Create a service with two env-vars
```bash
docker service create --env FOO=bar --env BAR=baz --name=test nginx:alpine
docker service inspect --format '{{json .Spec.TaskTemplate.ContainerSpec.Env }}' test | jq .
[
"FOO=bar",
"BAR=baz"
]
```
Update the service, with the intent to replace the value of `FOO` for a new value
```bash
docker service update --env-rm FOO --env-add FOO=updated-foo test
docker service inspect --format '{{json .Spec.TaskTemplate.ContainerSpec.Env }}' test | jq .
[
"BAR=baz"
]
```
Create a service with two labels
```bash
docker service create --label FOO=bar --label BAR=baz --name=test nginx:alpine
docker service inspect --format '{{json .Spec.Labels }}' test | jq .
{
"BAR": "baz",
"FOO": "bar"
}
```
Update the service, with the intent to replace the value of `FOO` for a new value
```bash
docker service update --label-rm FOO --label-add FOO=updated-foo test
docker service inspect --format '{{json .Spec.Labels }}' test | jq .
{
"BAR": "baz"
}
```
Create a service with two container labels
```bash
docker service create --container-label FOO=bar --container-label BAR=baz --name=test nginx:alpine
docker service inspect --format '{{json .Spec.TaskTemplate.ContainerSpec.Labels }}' test | jq .
{
"BAR": "baz",
"FOO": "bar"
}
```
Update the service, with the intent to replace the value of `FOO` for a new value
```bash
docker service update --container-label-rm FOO --container-label-add FOO=updated-foo test
docker service inspect --format '{{json .Spec.TaskTemplate.ContainerSpec.Labels }}' test | jq .
{
"BAR": "baz",
}
```

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().
This bug has been introduced by 395a6d560d
and produces following error message:
```
Template parsing error: template: :139:10: executing "" at <.ResourceLimitPids>: error calling ResourceLimitPids: runtime error: invalid memory address or nil pointer dereference

Both libaries provide similar functionality. We're currently using
Google Shlex in more places, so prefering that one for now, but we
could decide to switch to mattn/go-shellwords in future if that
library is considered better (it looks to be more actively maintained,
but that may be related to it providing "more features").

In situations where `~/.docker/config.json` was a symlink, saving
the file would replace the symlink with a file, instead of updating
the target file location;
mkdir -p ~/.docker
touch ~/real-config.json
ln -s ~/real-config.json ~/.docker/config.json
ls -la ~/.docker/config.json
# lrwxrwxrwx 1 root root 22 Jun 23 12:34 /root/.docker/config.json -> /root/real-config.json
docker login
# Username: thajeztah

The wrapping made the code harder to read (and in some cases destracted
from the actual code flow).
Some of these functions take too many arguments; instead of hiding that,
it probably better to make it apparent that something needs to be done
(and fix it :-)).

- change `validateResolveImageFlag()` to only perform _validation_,
and not combine it with modifying the option.
- use a `switch` instead of `if` in `validateResolveImageFlag()`
- `deployServices()`: break up some `switch` cases to make them
easier to read/understand the logic.

- TestParseRunAttach: use subtests to reduce cyclomatic complexity
- TestParseRunWithInvalidArgs: use subtests, and check if the expected
error is returned.
- Removed parseMustError() as it was mostly redundant

Before this change, a warning would be printed if the `~/.docker/config.json`
file was empty:
mkdir -p ~/.docker && touch ~/.docker/config.json
docker pull busybox
WARNING: Error loading config file: /root/.docker/config.json: EOF
Using default tag: latest
....
Given that we also accept an empty "JSON" file (`{}`), it should be
okay to ignore an empty file, as it's effectively a configuration file
with no custom options set.

I'm not sure if this fixes anything, however I have seen some weird
behavior on Windows where temp config files are left around and there
doesn't seem to be any errors reported.

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.

There's no need to perform an `os.Stat()` first, because
`os.Open()` also returns the same errors if the file does
not exist, or couldn't be opened for other reasons.

This prevents inconsistent errors when using a symlink, or when renaming

Previously we only set the platform when performing a pull, which is
only initiated if pull always is set, or if the image reference does not
exist in the daemon.
The daemon now supports specifying which platform you wanted on
container create so it can validate the image reference is the platform
you thought you were getting.

This is not currently used by the CLI, but can be used by
docker compose to bring parity on this feature with the
