This updates the pretty-print format of docker info to provide more
details on installed plugins, to help users find where a specific
plugin is installed (e.g. to update it, or to uninstall it).

This makes the containers have an expected console size not only for
`run` but also for `create`. Also remove the comment, as this is no
longer ignored on Linux daemon since e994efcf64c133de799f16f5cd6feb1fc41fade4

Wording and documentation still need to be updated, but will do
so in a follow-up.
Also removing the default "10 seconds" from the timeout flags, as
this default is not actually used, and may not match the actual
default (which is defined on the daemon side).

Formatting stats runs in a loop to refresh the stats for each container. This
patch makes some small performance improvments by reducing the use of Sprintf
in favor of concatenating strings, and using strconv directly where possible.

Before this change, the function could print an error in some cases, for example;
```bash
docker -H tcp://127.0.0.1:2375 info --format '{{.LoggingDriver}}'
template: :1:2: executing "" at <.LoggingDriver>: reflect: indirection through nil pointer to embedded struct field Info
```
With this patch applied, the error is handled gracefully, and when failing to
connect with the daemon, the error is logged;
```bash
docker -H tcp://127.0.0.1:2375 info --format '{{.LoggingDriver}}'
Cannot connect to the Docker daemon at tcp://127.0.0.1:2375. Is the docker daemon running?
docker -H tcp://127.0.0.1:2375 info --format '{{json .}}'
Cannot connect to the Docker daemon at tcp://127.0.0.1:2375. Is the docker daemon running?
{"ID":"","Containers":0,"..."}}
```
Note that the connection error is also included in the JSON `ServerErrors` field,
so that the information does not get lost, even if STDERR would be redirected;
```bash
docker -H tcp://127.0.0.1:2375 info --format '{{json .ServerErrors}}' 2> /dev/null
["Cannot connect to the Docker daemon at tcp://127.0.0.1:2375. Is the docker daemon running?"]

This test is very flaky, the retry loop runs for 550ms and some more, 750ms is
cleary not enough for everything to set and for the cli to return the tty resize
error. A sleep of 1.5 seconds in this test should be enough for the retry loop to
finish.

I some cases, for example if there is a heavy load, the initialization of the TTY size
would fail. This change makes the cli retry 10 times instead of 5 and we wait
incrementally from 10ms to 100ms

The code is similar to that used by the volume rm subcommand, however,
one difference I noticed was VolumeRemove takes the force flag/option
was a parameter. This isn't the case for NetworkRemove.
To get NetworkRemove to take a similar parameter, this would require
modifying the Docker daemon. For now this isn't a route I wish to take
when the code can be arrange to mimic the same behavior.

pkg/urlutil (despite its poorly chosen name) is not really intended as a
generic utility to handle URLs, and should only be used by the builder to
handle (remote) build contexts.
The `IsURL()` function only does a very rudimentary check for `http(s)://`
prefixes, without any other validation, but due to its name may give
incorrect expectations.
As we're deprecating this package for uses other than for build-contexts,
this patch replaces this instance of the utility for a local function.
While changing, also cleaned up some intermediate variables, and made
the logic slightly more descriptive.
Signed-off-by: Sebastiaan van Stijn <github@gone.nl>
This check doesn't really make sense because the client doesn't know on what
OS the daemon is really running.
The daemon uses the console size on creation when available (on windows).

Now that we no longer support kubernetes as orchestrator in the cli

This adds a new annotation to commands that are known to be frequently
used, and allows setting a custom weight/order for these commands to
influence in what order they appear in the --help output.
I'm not entirely happy with the implementation (we could at least use
some helpers for this, and/or make it more generic to group commands
in output), but it could be a start.
For now, limiting this to only be used for the top-level --help, but
we can expand this to subcommands as well if we think it makes sense
to highlight "common" / "commonly used" commands.

Before this change, the top-level flags, such as `--config` and `--tlscacert`,
were printed at the top of the `--help` output. These flags are not used
frequently, and putting them at the top, made the information that's more
relevant to most users harder to find.
This patch moves the top-level flags for the root command (`docker`) to the
bottom of the help output, putting the subcommands more prominent in view.
