Use designated test domains (RFC2606) in tests
Some tests were using domain names that were intended to be "fake", but are
actually registered domain names (such as mycorp.com).

Even though we were not actually making connections to these domains, it's
better to use domains that are designated for testing/examples in RFC2606:
https://tools.ietf.org/html/rfc2606

Tibor Vass 48d30b5b32 Use golang.org/x/sys/execabs
On Windows, the os/exec.{Command,CommandContext,LookPath} functions
resolve command names that have neither path separators nor file extension
(e.g., "git") by first looking in the current working directory before
looking in the PATH environment variable.
Go maintainers intended to match cmd.exe's historical behavior.

However, this is pretty much never the intended behavior and as an abundance of precaution
this patch prevents that when executing commands.
Example of commands that docker.exe may execute: `git`, `docker-buildx` (or other cli plugin), `docker-credential-wincred`, `docker`.

Note that this was prompted by the [Go 1.15.7 security fixes](https://blog.golang.org/path-security), but unlike in `go.exe`,
the windows path lookups in docker are not in a code path allowing remote code execution, thus there is no security impact on docker.

Akihiro Suda 62a15c16fc commandconn: set SysProcAttr.Setsid
Setting `Setsid` is needed for SSH connection helper with `ProxyCommand`
config, so as to detach TTY.

e.g.

  $ cat ~/.ssh/config
  Host foo
    Hostname foo
    ProxyCommand ssh -W %h:%p bastion
  $ DOCKER_HOST=ssh://foo docker run -it --rm alpine
  / #

Fix #1707

Ian Campbell 891b3d953e cli-plugins: use `docker system dial-stdio` to call the daemon
This means that plugins can use whatever methods the monolithic CLI supports,
which is good for consistency.

This relies on `os.Args[0]` being something which can be executed again to
reach the same binary, since it is propagated (via an envvar) to the plugin for
this purpose. This essentially requires that the current working directory and
path are not modified by the monolithic CLI before it launches the plugin nor
by the plugin before it initializes the client. This should be the case.

Previously the fake apiclient used by `TestExperimentalCLI` was not being used,
since `cli.Initialize` was unconditionally overwriting it with a real one
(talking to a real daemon during unit testing, it seems). This wasn't expected
nor desirable and no longer happens with the new arrangements, exposing the
fact that no `pingFunc` is provided, leading to a panic. Add a `pingFunc` to
the fake client to avoid this.

Akihiro Suda 6f61cf053a support SSH connection
e.g. docker -H ssh://me@server

The `docker` CLI also needs to be installed on the remote host to
provide `docker system dial-stdio`, which proxies the daemon socket to stdio.

Please refer to docs/reference/commandline/dockerd.md .
