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.

SharedSize support was introduced in API version 1.42. This field was

Now client have the possibility to set the console size of the executed
process immediately at the creation. This makes a difference for example
when executing commands that output some kind of text user interface
which is bounded by the console dimensions.

On Linux the daemon was not respecting the HostConfig.ConsoleSize
property and relied on cli initializing the tty size after the container
was created. This caused a delay between container creation and
the tty actually being resized.
This is also a small change to the api description, because
HostConfig.ConsoleSize is no longer Windows-only.

This was added in 93c3e6c91e, at which time only
some basic handling of non-succesful status codes was present;

The wrapResponseError() utility converted some specific errors, but in
doing so, could hide the actual error message returned by the daemon.
In addition, starting with 38e6d474af,
HTTP status codes were already mapped to their corresponding errdefs
types on the client-side, making this conversion redundant.
This patch removes the wrapResponseError() utility; it's worth noting
that some error-messages will change slightly (as they now return the
error as returned by the daemon), but may cointain more details as
before, and in some cases prevents hiding the actual error.

The API defines a default limit for searches, but when removing the
default from the cli, the client still sends "0" as a limit, which
is not allowed by existing versions of the API:
docker search --limit=0 busybox
Error response from daemon: Limit 0 is outside the range of [1, 100]
This patch changes the client so that no limit is sent if none was set ("0"),
allowing the daemon to use its (or the registry's) default.

This adds consts for the environment variables that are supported
by the client. These environment variables are unlikely to change,
or at least, unlikely to be removed, but having consts allows for
them to be documented.
I did not change all occurrences of these variables to use the const,
as they're used in various tests, and it's ok to use a fixture for
those, but it's nice to have a const available for (external) consumers
of the client package, and to have their purpose (and caveats)
documented in the code.

- Improve documentation of various functions to better describe their behavior.
- Rename some variables to be more descriptive (as this is client code, used
by external consumers, it's nice to be a bit more explicit).
- Remove a redundant check in `WithVersionFromEnv()`, as `WithVersion()`
already checks for empty values.

This test was setting the non-exported `Client.basePath` directly, however,
it was setting it to a value that would never realistically happen, because
`NewClientWithOpts()` initializes the Client with the default API version:
ea5b4765d9/client/client.go (L119-L130)
Which is used by `getAPIPath()` to construct the URL/path:
ea5b4765d9/client/client.go (L176-L190)
While this didn't render the test "invalid", using a Client that's constructed
in the usual way, makes it more representative.
Given that we deprecated (but still support) the non-versioned API paths, with
the exception of the `/_ping` API endpoint, we should probably change `getAPIPath()`
to default to the "current version", instead of allowing it to use an empty string.

- avoid accessing non-exported fields where possible, and test using accessors
instead, so that we're closer to how it's actually used.
- use a variable or const for "expected" in some tests, so that "expected" is
printed as part of the test-failure output (instead of just a "value").
- swap the order of "actual" and "expected" for consistency, and to make it
easier to see what the "expected" value is in some cases ("expected" on the
right, so that it reads `val (actual) != val (expected)`).
- don't set fields in the Ping response that are not relevant to the test.
- rename some variables for consistency.

As caught by gosimple:
client/client.go:138:14: S1040: type assertion to the same type: c.client.Transport already has type http.RoundTripper (gosimple)
if _, ok := c.client.Transport.(http.RoundTripper); !ok {

This check was originally added in dc9f5c2ca3, to
check if the passed option was a `http.Transport`, and later changed in
e345cd12f9 to check for `http.RoundTripper` instead.
Client.client is a http.Client, for which the Transport field is a RoundTripper,
so this check is redundant.
