This refactors the way networking options are parsed, and makes the
client able to pass options for multiple networks. Currently, the
daemon does not yet accept multiple networks when creating a container,
and will produce an error.
For backward-compatibility, the following global networking-related
options are associated with the first network (in case multiple
networks are set);
- `--ip`
- `--ip6`
- `--link`
- `--link-local-ip`
- `--network-alias`
Not all of these options are supported yet in the advanced notation,
but for options that are supported, setting both the per-network option
and the global option will produce a "conflicting options" error.

The commit contains cli changes to support driver options for a network in
docker run and docker network connect cli's. The driver-opt, aliases is now
supported in the form of csv as per network option in service commands in
swarm mode since docker/cli#62 . This commit extends this support to docker
run command as well.
For docker connect command `--driver-opt` is added to pass driver specific
options for the network the container is connecting to.

Instead of using an `if else if else`, switch to a sequence of independent
`if` blocks containing a `return`.
Instead of defining a return variable and updating it in the `if` blocks
and returning at the end, make each `if` block return the desired value
independenly.

Previously if the Docker engine was not running the behaviour of
commands would vary depending on whether the --debug flag was provided.
For example, consider `docker logout`:
$ docker logout
Not logged in to
-- note the missing server URL
$ docker --debug logout
Warning: failed to get default registry endpoint from daemon (Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?). Using system default: https://index.docker.io/v1/
Not logged in to https://index.docker.io/v1/
-- note the server URL is present
This patch makes only the debug printing conditional on the `--debug` flag,
not the return value.

As pointed out in #1459, docker cli fails to detect that the input is a tarball,
in case it is generated by `git archive --format=tgz`.
This happens because `git archive` adds some metadata to the initial tar header,
and so it is more than 1 block (of 512 bytes) long, while we only provide 1 block
to archive/tar.Next() and it fails.
To fix, give it 2 blocks :)

This adds validation to `docker container run` / `docker container create`;
Validation of labels provided through flags was removed in 31dc5c0a9a,
after the validation was changed to fix labels without values, and to prevent
labels from being expanded with environment variables in 2b17f4c8a8
However, now empty label names from _files_ (`--label-file`) followed different
validation rules than labels passed through `--label`.
This patch adds back minimal validation for labels passed through the command-line
Before this patch:
```bash
docker container create \
--name label \
--label==with-leading-equal-sign \
--label=without-value \
--label=somelabel=somevalue \
--label " = " \
--label=with-quotes-in-value='{"foo"}' \
--label='with"quotes"in-key=test' \
busybox
docker container inspect --format '{{json .Config.Labels}}' label
```
```json
{
"": "with-leading-equal-sign",
" ": " ",
"somelabel": "somevalue",
"with\"quotes\"in-key": "test",
"with-quotes-in-value": "{\"foo\"}",
"without-value": ""
}
```
After this patch:
```bash
docker container create \
--name label \
--label==with-leading-equal-sign \
--label=without-value \
--label=somelabel=somevalue \
--label " = " \
--label=with-quotes-in-value='{"foo"}' \
--label='with"quotes"in-key=test' \
busybox
invalid argument "=with-leading-equal-sign" for "-l, --label" flag: invalid label format: "=with-leading-equal-sign"
```

This patch fixes a bug where labels use the same behavior as `--env`, resulting
in a value to be copied from environment variables with the same name as the
label if no value is set (i.e. a simple key, no `=` sign, no value).
An earlier pull request addressed similar cases for `docker run`;
2b17f4c8a8, but this did not address the
same situation for (e.g.) `docker service create`.
Digging in history for this bug, I found that use of the `ValidateEnv`
function for labels was added in the original implementation of the labels feature in
abb5e9a077 (diff-ae476143d40e21ac0918630f7365ed3cR34)
However, the design never intended it to expand environment variables,
and use of this function was either due to either a "copy/paste" of the
equivalent `--env` flags, or a misunderstanding (the name `ValidateEnv` does
not communicate that it also expands environment variables), and the existing
`ValidateLabel` was designed for _engine_ labels (which required a value to
be set).
Following the initial implementation, other parts of the code followed
the same (incorrect) approach, therefore leading the bug to be introduced
in services as well.
This patch:
- updates the `ValidateLabel` to match the expected validation
rules (this function is no longer used since 31dc5c0a9a),
and the daemon has its own implementation)
- corrects various locations in the code where `ValidateEnv` was used instead of `ValidateLabel`.
Before this patch:
```bash
export SOME_ENV_VAR=I_AM_SOME_ENV_VAR
docker service create --label SOME_ENV_VAR --tty --name test busybox
docker service inspect --format '{{json .Spec.Labels}}' test
{"SOME_ENV_VAR":"I_AM_SOME_ENV_VAR"}
```
After this patch:
```bash
export SOME_ENV_VAR=I_AM_SOME_ENV_VAR
docker service create --label SOME_ENV_VAR --tty --name test busybox
docker container inspect --format '{{json .Config.Labels}}' test
{"SOME_ENV_VAR":""}

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;
```

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

- 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

This happens on Windows when dialing a named pipe (a path which is used by CLI
plugins), in that case some debugging shows:
DEBU[0000] conn is a *winio.win32MessageBytePipe
DEBU[0000] conn is a halfReadCloser: false
DEBU[0000] conn is a halfWriteCloser: true
the raw stream connection does not implement halfCloser
In such cases we can simply wrap with a nop function since closing for read
isn't too critical.
