Of both "--quiet" and "--format" are set, --quiet takes precedence. This
patch adds a warning to inform the user that their custom format is not
used:
docker ps --format='{{.Image}}'
ubuntu:22.04
alpine
docker ps --format='{{.Image}}' --quiet
WARNING: Ignoring custom format, because both --format and --quiet are set.
40111f61d5c5

The warning is printed on STDERR, so can be redirected:
docker ps --format='{{.Image}}' --quiet 2> /dev/null
40111f61d5c5
482efdf39fac
The warning is only shown if the format is set using the "--format" option.
No warning is shown if a custom format is set through the CLI configuration
file:
mkdir -p ~/.docker/
echo '{"psFormat": "{{.Image}}"}' > ~/.docker/config.json
docker ps
ubuntu:22.04
alpine
docker ps --quiet

Previously, the formatter would ignore the quiet option if a custom format
was passed; this situation was handled in runPs(), where custom formats
would only be applied if the quiet option was not set, but only if the
format was set in the CLI's config.
This patch updates NewContainerFormat() to do the same, even if a `--format`
was passed on the command-line.
This is a change in behavior, so may need some discussion; possible alternatives;
- produce an error if both `--format` and `--quiet` are passed
- print a warning if both are passed (but use the logic from this patch)
Before this patch:
```console
docker ps --format '{{.Image}}'
ubuntu:22.04
alpine
docker ps --format '{{.Image}}' --quiet
ubuntu:22.04
alpine
mkdir -p ~/.docker/
echo '{"psFormat": "{{.Image}}"}' > ~/.docker/config.json
docker ps
ubuntu:22.04
alpine
docker ps --quiet
ubuntu:22.04
alpine
```
With this patch applied:
```console
docker ps --format '{{.Image}}'
ubuntu:22.04
alpine
docker ps --format '{{.Image}}' --quiet
40111f61d5c5
482efdf39fac
mkdir -p ~/.docker/
echo '{"psFormat": "{{.Image}}"}' > ~/.docker/config.json
docker ps
ubuntu:22.04
alpine
docker ps --quiet

- do an early check if a custom format is specified either through the
command-line, or through the cli's configuration, before adjusting
the options (to add "size" if needed).
- also removes a redundant `options.Size = opts.size` line, as this value is
already copied at the start of buildContainerListOptions()
- Update NewContainerFormat to use "table" format as a default if no format
was given.

Before this patch, using a template that used templating functions (such as
`lower` or `json`) caused the command to fail in the pre-processor step (in
`buildContainerListOptions`):
docker ps --format='{{upper .Names}}'
template: :1:8: executing "" at <.Names>: invalid value; expected string
This problem was due to the pre-processing using a different "context" type than
was used in the actual template, and custom functions to not be defined when
instantiating the Go template.
With this patch, using functions in templates works correctly:
docker ps --format='{{upper .Names}}'

Move the remaining test with the others, and rename it from
`TestBuildContainerListOptions` to `TestContainerListBuildContainerListOptions`,
so that it has the same prefix as the other tests.
