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.

If a blank nodeID was previously passed in it resulted in a node list
request. The response would then fail to umarshal into a `Node`
type returning a JSON error.
This adds an extra validation to all inspect calls to check that the ID
that is required is provided and if not return an error.

This fix tries to address the proposal raised in 28946
to support plugins in `docker inspect`.
The command `docker inspect` already supports
"container", "image", "node", "network", "service", "volume", "task".
However, `--type plugin` is not supported yet at the moment.
This fix address this issue by adding the support of `--type plugin`
for `docker inspect`.
An additional integration test has been added to cover the changes.
This fix fixes 28946.
