ensureReaderClosed was designed to be usable regardless if a response
was nil (error) or non-nil (success). Some code-paths were optimized to
avoid using a defer (which used to have an overhead), but the overhead
of defer is neglectable in current versions of Go, and some of these
optimizations made the logic more complicated (and err-prone).
This patch switches to use a defer for all places.

While it is imported by both the client and the daemon, values of the
PluginCreateOptions struct are not marshaled or unmarshaled. The only
field is mapped to and from an HTTP query parameter. Furthermore, this
options type is the odd one out: the daemon uses types in
api/types/backend to pass options around for the other plugin lifecycle
operations. Move the PluginCreateOptions type into client, and define a
new PluginCreateConfig struct in api/types/backend for the daemon to use
alongside PluginRmConfig, PluginEnableConfig and PluginDisableConfig.

These comments were added to enforce using the correct import path for
our packages ("github.com/docker/docker", not "github.com/moby/moby").
However, when working in go module mode (not GOPATH / vendor), they have
no effect, so their impact is limited.
Remove these imports in preparation of migrating our code to become an
actual go module.

Unlike a plain `net/http/client.Do()`, requests made through client/request
use the `sendRequest` function, which parses the server response, and may
convert non-transport errors into errors (through `cli.checkResponseErr()`).
This means that we cannot assume that no reader was opened if an error is
returned.
This patch changes various locations where `ensureReaderClosed` was only
called in the non-error situation, and uses a `defer` to make sure it's
always called.
`ensureReaderClosed` itself already checks if the response's body was set,
so in situations where the error was due to a transport error, calling
`ensureReaderClosed` should be a no-op.

Since Go 1.7, context is a standard package. Since Go 1.9, everything
that is provided by "x/net/context" is a couple of type aliases to
types in "context".
Many vendored packages still use x/net/context, so vendor entry remains
for now.

At the "Build image from Dockerfile" section in the API docs
the Content-Type header is missing.
In addition, some parts in the code are still setting the
Content-Type header to application/tar while it was changed
to application/x-tar since 16th September 2015.
