In previous versions of the Docker API, `system prune --volumes` and `volume prune`
would remove all dangling volumes. With API v1.42, this was changed so that only
anonymous volumes would be removed unless the all filter was specified.
Some of the docs were updated in #4218, however, there were a couple of places
left that didn't make the anonymous vs named volumes distinction clear.
This replaces #4079, which was bitrotted by #4218. See also #4028.
Closes#4079.

The warning, printed before running `docker system prune` was printing the
filters in JSON format.
This patch attempts to make the output human readable;
- updating the code, and template to print filters individually
- reducing the indentation (which was quite deep)
Before this patch was applied;
```
docker system prune --filter until=24h --filter label=hello-world --filter label!=foo=bar --filter label=bar=baz
WARNING! This will remove:
- all stopped containers
- all networks not used by at least one container
- all dangling images
- all dangling build cache
- Elements to be pruned will be filtered with:
- label={"label":{"bar=baz":true,"hello-world":true},"label!":{"foo=bar":true},"until":{"24h":true}}
Are you sure you want to continue? [y/N]
```
With this patch applied;
```
WARNING! This will remove:

The warning, printed before runing docker system prune was missing any filter
that was set in the configuration file. In addition, the warning prefixes the
filters with `label=`, which is no longer accurate, now that the prune command
also supports "until" as a filter.
Before this change, only the filters set on the command-line were shown,
and any filter set in the configuration file was missing;
```
mkdir -p ./test-config
echo '{"pruneFilters": ["label!=never=remove-me", "label=remove=me"]}' > test-config/config.json
docker --config=./test-config system prune --filter until=24h --filter label=hello-world --filter label!=foo=bar --filter label=bar=baz
WARNING! This will remove:
- all stopped containers
- all networks not used by at least one container
- all dangling images
- all dangling build cache
- Elements to be pruned will be filtered with:
- label={"label":{"bar=baz":true,"hello-world":true},"label!":{"foo=bar":true},"until":{"24h":true}}
Are you sure you want to continue? [y/N]
```
With this patch applied, both options from the commandline and options set
in the configuration file are shown;
```
mkdir -p ./test-config
echo '{"pruneFilters": ["label!=never=remove-me", "label=remove=me"]}' > test-config/config.json
docker --config=./test-config system prune --filter until=24h --filter label=hello-world --filter label!=foo=bar --filter label=bar=baz
WARNING! This will remove:
- all stopped containers
- all networks not used by at least one container
- all dangling images
- all dangling build cache
- Elements to be pruned will be filtered with:
- filter={"label":{"bar=baz":true,"hello-world":true,"remove=me":true},"label!":{"foo=bar":true,"never=remove-me":true},"until":{"24h":true}}

Since go 1.7, "context" is a standard package. Since go 1.9,
x/net/context merely provides some types aliased to those in
the standard context package.
The changes were performed by the following script:
for f in $(git ls-files \*.go | grep -v ^vendor/); do
sed -i 's|golang.org/x/net/context|context|' $f
goimports -w $f
for i in 1 2; do
awk '/^$/ {e=1; next;}
/\t"context"$/ {e=0;}
{if (e) {print ""; e=0}; print;}' < $f > $f.new && \
mv $f.new $f
goimports -w $f
done
done
[v2: do awk/goimports fixup twice]

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

Note that `docker volume prune` does not have this problem, and produces an

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.

Volumes tend to carry important data and pruning them on `docker system
prune` can easily cause unwanted data loss.
Let's play it safe and not prune volumes on `system prune` by default,
and instead provide an option.
