The tabwriter was configured to have a min-width for columns of 20 positions.
This seemed quite wide, and caused smaller columns to be printed with a large
gap between.

Update the list of overrides for table headers so that columns using split or

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}}'

The State field allows printing the container state without

With this patch, the container's state can be printed independently:

created
```
```bash
docker ps -a --format 'table {{.Names}}\t{{.State}}\t{{.Status}}'

- make it possible to extract the formatter implementation from the
"common" code, that way, the formatter package stays small
- extract some formatter into their own packages
This is essentially moving the "formatter" implementation of each type
in their respective packages. The *main* reason to do that, is to be
able to depend on `cli/command/formatter` without depending of the
implementation detail of the formatter. As of now, depending on
`cli/command/formatter` means we depend on `docker/docker/api/types`,
`docker/licensing`, … — that should not be the case. `formatter`
should hold the common code (or helpers) to easily create formatter,
not all formatter implementations.

Port mappings in `docker service ls` are quite verbose, and occupy a lot of
space when ranges of ports are published.
This patch improves the output by reconstructing ranges of ports.
Given the following service;
$ docker service create \
-p 60-61:60-61 \
-p 62:61 \
-p 80:80 \
-p 81:80 \
-p 90-95:90-95 \
-p 90-92:90-92/udp \
-p 93-96:93-96/udp \
--name foo \
nginx:alpine
Before this patch is applied:
$ docker service ls
ID NAME MODE REPLICAS IMAGE PORTS
u1kwguv841qg foo replicated 1/1 nginx:alpine *:60->60/tcp,*:61->61/tcp,*:62->61/tcp,*:80->80/tcp,*:81->80/tcp,*:90->90/tcp,*:91->91/tcp,*:92->92/tcp,*:93->93/tcp,*:94->94/tcp,*:95->95/tcp,*:90->90/udp,*:91->91/udp,*:92->92/udp,*:93->93/udp,*:94->94/udp,*:95->95/udp,*:96->96/udp
After this patch is applied:
$ docker service ls
ID NAME MODE REPLICAS IMAGE PORTS
u1kwguv841qg foo replicated 1/1 nginx:alpine *:60-62->60-61/tcp,*:80-81->80/tcp,*:90-95->90-95/tcp,*:90-96->90-96/udp
Additional enhancements can still be made, and marked as TODO in this change;
- combine non-consecutive ports mapped to a single port (`80->80`, `81->80`,
`84->80`, `86->80`, `87->80`); to be printed as `*:80-81,84,86-87->80`.
- combine `tcp` and `udp` mappings if their port-mapping is the same;
print `*:80-81->80-81/tcp+udp` instead of `*:80-81->80-81/tcp, *:80-81->80-81/udp`

The `docker container stats` output has a column (`CONTAINER`), that shows either
the container _id_ or container _name_, depending on the arguments given.
For example, running `docker container stats foobar` shows:
CONTAINER CPU % MEM USAGE / LIMIT MEM % NET I/O BLOCK I/O PIDS
foobar 0.00% 1.938MiB / 1.952GiB 0.10% 782B / 0B 4.11MB / 0B 2
Whereas `docker container stats 67b2525d8ad1` (`67b2525d8ad1` being the ID for
container `foobar`) shows:
CONTAINER CPU % MEM USAGE / LIMIT MEM % NET I/O BLOCK I/O PIDS
67b2525d8ad1 0.00% 1.938MiB / 1.952GiB 0.10% 916B / 0B 4.11MB / 0B 2
This behavior is confusing.
This patch updates the default output format for `docker stats` to use separate
columns for container ID and container Name (similar to `docker container ls`).
With this patch applied, both commands show the same output:
$ docker container stats foobar
CONTAINER ID NAME CPU % MEM USAGE / LIMIT MEM % NET I/O BLOCK I/O PIDS
67b2525d8ad10bb236a49960e93c09993b0baabeef12c2d46cd5f4fbb6f4808c foobar 0.00% 1.938MiB / 1.952GiB 0.10% 1.25kB / 0B 4.11MB / 0B 2
$ docker container stats 67b2525d8ad1
CONTAINER ID NAME CPU % MEM USAGE / LIMIT MEM % NET I/O BLOCK I/O PIDS
67b2525d8ad10bb236a49960e93c09993b0baabeef12c2d46cd5f4fbb6f4808c foobar 0.00% 1.938MiB / 1.952GiB 0.10% 1.31kB / 0B 4.11MB / 0B 2
Users that want to use the old format can configure a custom format in the
cli configuration file (`~/.docker/config.json`);
on Linux:
{
"statsFormat" : "table {{.Container}}\t{{.CPUPerc}}\t{{.MemUsage}}\t{{.MemPerc}}\t{{.NetIO}}\t{{.BlockIO}}\t{{.PIDs}}"
}
on Windows:
{
"statsFormat" : "table {{.Container}}\t{{.CPUPerc}}\t{{.MemUsage}}\t{{.NetIO}}\t{{.BlockIO}}"
}
