This patch adds the untilRemoved option to the ContainerWait API which
allows the client to wait until the container is not only exited but
also removed.
This patch also adds some more CLI integration tests for waiting for a

From Go 1.8 HTTP client redirect behaviour is changed:
When status code is 301, 307 or 308, the client
automatically converts it to a new HTTP request.
This behaviour change manifests in the client in that
before the 301 was not followed and the client did not generate
an error, but now results in an error message:
"Error response from daemon: page not found."
To fix that a new redirect policy is forced by setting
HTTP Client's CheckRedirect.
That policy is to return an error for any 301, 307 or 308
in the response's status code to a non-GET request.
The error message specifies that the daemon could not
process the request and it is probably due to bad
arguments that were provided by the user.

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.

Docker 1.13 and up allows a client to communicate
with older daemons. As a result, flags may be
present that are not supported by the older daemon.
The client already _hides_ flags that are not
supported yet, but this doesn't present users
from using those flags.
This change shows an error if a flag is used
that is not supported by the daemon (either
based on the API version, or because experimental
features are not enabled).
Note that for some options, a check is already
in place in the API client. For those
options, this is just a minor enhancement
to more clearly indicate which _flag_ is
not supported.
Before this change;
DOCKER_API_VERSION=1.24 docker run -d --stop-timeout=30 busybox top
mjfyt3qpvnq0iwmun3sjwth9i
echo -e "FROM busybox\nRUN echo foo > bar" | DOCKER_API_VERSION=1.24 docker build --squash -
"squash" requires API version 1.25, but the Docker server is version 1.24
After this change;
DOCKER_API_VERSION=1.24 docker run -d --stop-timeout=30 busybox top
"--stop-timeout" requires API version 1.25, but the Docker daemon is version 1.24
echo -e "FROM busybox\nRUN echo foo > bar" | DOCKER_API_VERSION=1.24 docker build --squash -
"--squash" requires API version 1.25, but the Docker daemon is version 1.24

This allows a plugin to be upgraded without requiring to
uninstall/reinstall a plugin.
Since plugin resources (e.g. volumes) are tied to a plugin ID, this is
important to ensure resources aren't lost.
The plugin must be disabled while upgrading (errors out if enabled).
This does not add any convenience flags for automatically
disabling/re-enabling the plugin during before/after upgrade.
Since an upgrade may change requested permissions, the user is required
to accept permissions just like `docker plugin install`.

Docker 1.13 moves the `--rm` flag to the daemon,
through an AutoRemove option in HostConfig.
When using API 1.24 and under, AutoRemove should not be
used, even if the daemon is version 1.13 or above and
"supports" this feature.
This patch fixes a situation where an 1.13 client,
talking to an 1.13 daemon, but using the 1.24 API
version, still set the AutoRemove property.
As a result, both the client _and_ the daemon
were attempting to remove the container, resulting
in an error:
ERRO[0000] error removing container: Error response from daemon:
removal of container ce0976ad22495c7cbe9487752ea32721a282164862db036b2f3377bd07461c3a
is already in progress
In addition, the validation of conflicting options
is moved from `docker run` to `opts.parse()`, so
that conflicting options are also detected when
running `docker create` and `docker start` separately.
To resolve the issue, the `AutoRemove` option is now
always set to `false` both by the client and the
daemon, if API version 1.24 or under is used.

In cases where there is high latency (ie, not-local network)
`waitExitOrRemoved` was not receiving events for short-lived containers.
This caused the client to hang while waiting for a notification that the
container has stopped.
This happens because `client.Events()` returns immediately and spins a
goroutine up to process events. The problem here is it returns before
the request to the events endpoint is even made.
Even without high-latency issues, there is no guarantee that the
goroutine is even scheduled by the time the function returns.

This reverts 26103. 26103 was trying to make it so that if someone did:
docker build --build-arg FOO .
and FOO wasn't set as an env var then it would pick-up FOO from the
Dockerfile's ARG cmd. However, it went too far and removed the ability
to specify a build arg w/o any value. Meaning it required the --build-arg
param to always be in the form "name=value", and not just "name".
This PR does the right fix - it allows just "name" and it'll grab the value
from the env vars if set. If "name" isn't set in the env then it still needs
to send "name" to the server so that a warning can be printed about an
unused --build-arg. And this is why buildArgs in the options is now a
*string instead of just a string - 'nil' == mentioned but no value.
