Some network environments may have NATs, proxies, or gateways which
kill idle connections. There are many Docker API operations which may
be idle for long periods of time (such as ContainerWait and ContainerAttach)
and may result in unexpected connection closures or hangs if TCP keepalives
are not used.
This patch updates the default HTTP transport used by the Docker client
package to enable TCP Keep-Alive with a keep-alive interval of 30 seconds.
It also sets a connect timeout of 30 seconds.

Ports that were picked from the ephemeral port range
were presented as `*:0->80/tcp`.
This patch changes the presentation to use the
actually assigned port, instead of the port specified
in `Endpoint.Spec` (which is always empty/zero (`0`))

The "until" filter is supported by all object types, except for
volumes.
Before this patch, the "until" filter would attempted to be used for the volume
prune endpoint, resulting in an error being returned by the daemon, and
further prune endpoints (networks, images) to be skipped.
$ docker system prune --filter until=24h --filter label=label.foo=bar
WARNING! This will remove:
- all stopped containers
- all volumes not used by at least one container
- all networks not used by at least one container
- all dangling images

With this patch, an error is produced instead, preventing "partial" prune.
$ docker system prune --filter until=24h --filter label=foo==bar --volumes
ERROR: The "until" filter is not supported with "--volumes"
Note that `docker volume prune` does not have this problem, and produces an
error if the `until` filter is used;
$ docker volume prune --filter until=24h

Adapt "image prune" and "build cache prune" to have
the same signature as the other prune commands, so
that they can all be added to the "pruneFuncs" array.

This commit changes the order stacks and nodes are displayed.
For example, running "docker stack ls" is expected to
display the following list:
NAME SERVICES
service-1 1
service-2 1
service-10 1
However, currently this is what is printed:
NAME SERVICES
service-1 1
service-10 1
service-2 1
To fix this, "docker stack ls" and "docker node ls" are using
natural sorting to make it more human readable.

When running `docker stack rm <some stack>` against an older daemon,
a warning was printed for "configs" being ignored;
WARNING: ignoring "configs" (requires API version 1.30, but the Docker daemon API version is 1.26)
Given that an old daemon cannot _have_ configs, there should not be
a need to warn, or _attempt_ to remove these resources.
This patch removes the warning, and skips fetching (and removing)
configs.
A check if _secrets_ are supported by the daemon is also added,
given that this would result in an error when attempted against
an older (pre 1.13) daemon.
There is one situation where this could lead to secrets or
configs being left behind; if the client is connecting to a
daemon that _does_ support secrets, configs, but the API version
is overridden using `DOCKER_API_VERSION`, no warning is printed,
and secrets and configs are not attempted to be removed.
Given that `DOCKER_API_VERSION` is regarded a feature for
debugging / "power users", it should be ok to ignore this.
