Commit e6907243af applied a fix for situations
where the client was configured with API-version negotiation, but did not yet
negotiate a version.
However, the checkVersion() function that was implemented copied the semantics
of cli.NegotiateAPIVersion, which ignored connection failures with the
assumption that connection errors would still surface further down.
However, when using the result of a failed negotiation for NewVersionError,
an API version mismatch error would be produced, masking the actual connection
error.
This patch changes the signature of checkVersion to return unexpected errors,
including failures to connect to the API.
Before this patch:
docker -H unix:///no/such/socket.sock secret ls
"secret list" requires API version 1.25, but the Docker daemon API version is 1.24
With this patch applied:
docker -H unix:///no/such/socket.sock secret ls
Cannot connect to the Docker daemon at unix:///no/such/socket.sock. Is the docker daemon running?

We try to perform API-version negotiation as lazy as possible (and only execute
when we are about to make an API request). However, some code requires API-version
dependent handling (to set options, or remove options based on the version of the
API we're using).
Currently this code depended on the caller code to perform API negotiation (or
to configure the API version) first, which may not happen, and because of that
we may be missing options (or set options that are not supported on older API
versions).
This patch:
- splits the code that triggered API-version negotiation to a separate
Client.checkVersion() function.
- updates NewVersionError to accept a context
- updates NewVersionError to perform API-version negotiation (if enabled)
- updates various Client functions to manually trigger API-version negotiation

Repro steps:
- Run Docker Desktop
- Run `docker run busybox tail -f /dev/null`
- Run `pkill "Docker Desktop"
Expected:
An error message that indicates that Docker Desktop is shutting down.
Actual:
An error message that looks like this:
```
error waiting for container: invalid character 's' looking for beginning of value
```
here's an example:
https://github.com/docker/for-mac/issues/6575#issuecomment-1324879001
After this change, you get an error message like:
```
error waiting for container: copying response body from Docker: unexpected EOF
```
which is a bit more explicit.

The client would always send a value, even if no `condition` was set;
Calling POST /v1.41/containers/foo/wait?condition=
This patch changes the client to not send the parameter if it's empty (and the
API default value should be used).

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.

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
created container and waiting with the new --until-removed flag.

Apply container wait changes to API 1.30
The set of changes to the containerWait API missed the cut for the
Docker 17.05 release (API version 1.29). This patch bumps the version
checks to use 1.30 instead.
This patch also makes a minor update to a testfile which was added to
the builder/dockerfile package.

- Update ContainerWait backend interface to not return pointer values
for container.StateStatus type.
- Updated container state's Wait() method comments to clarify that a
context MUST be used for cancelling the request, setting timeouts,
and to avoid goroutine leaks.
- Removed unnecessary buffering when making channels in the client's
ContainerWait methods.
- Renamed result and error channels in client's ContainerWait methods
to clarify that only a single result or error value would be sent
on the channel.
