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.

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":""}

This changes the experimental --console flag to --progress following
feedback indicating avoidable confusion.
In addition to naming changes, the help output now has an additional
clarification, specifically: container output during builds are only
shown when progress output is set to plain. Not mentioning this was also
a big cause of confusion.

parsing an environment file should give an error in case a zero-length
variable name (definition w/o a variable name) is encountered.
previously these lines went through unnoticed not informing the user about
a potential configuration error.

previously docker did import environment variables if they were present
but created them if they were not when it was asked via a --env-file
cli option to import but not create them.
fix is to only import the variable into the environment if it is present.
additionally do not import variable names of zero-length (which are lines
w/ a potential variable definition w/o a variable name).

test to show current behavior is wrong at parsing an environment file
defining an undefined variable - it must not be defined!
NOTE: this test assume the $HOME variable is always set (see POSIX, this
normally is the case, e.g. the test suite remains stable).

`--label-file` has the exact same behavior as `--env-file`, meaning any
placeholder (i.e. a simple key, no `=` sign, no value), it will get the
value from the environment variable.
For `--label-file` it should just add an empty label.

I noticed that we're using a homegrown package for assertions. The
functions are extremely similar to testify, but with enough slight
differences to be confusing (for example, Equal takes its arguments in a
different order). We already vendor testify, and it's used in a few
places by tests.
I also found some problems with pkg/testutil/assert. For example, the
NotNil function seems to be broken. It checks the argument against
"nil", which only works for an interface. If you pass in a nil map or
slice, the equality check will fail.
In the interest of avoiding NIH, I'm proposing replacing
pkg/testutil/assert with testify. The test code looks almost the same,
but we avoid the confusion of having two similar but slightly different
assertion packages, and having to maintain our own package instead of
using a commonly-used one.
In the process, I found a few places where the tests should halt if an
assertion fails, so I've made those cases (that I noticed) use "require"
instead of "assert", and I've vendored the "require" package from
testify alongside the already-present "assert" package.

This fix made several updates:
1. Update opts.MemBytes so that default value will not show up.
The reason is that in case a default value is decided by daemon,
instead of client, we actually want to not show default value.
2. Move `docker run/create/build` to use opts.MemBytes for `--shm-size`
This is to bring consistency between daemon and docker run
3. docs updates.

This fix fixes issue raised in 29492 where it was not
possible to specify a default `--default-shm-size` in daemon
configuration for each `docker run``.
The flag `--default-shm-size` which is reloadable, has been
added to the daemon configuation.
Related docs has been updated.
This fix fixes 29492.
