The `~/.dockercfg` file was replaced by `~/.docker/config.json` in 2015
(github.com/docker/docker/commit/18c9b6c6455f116ae59cde8544413b3d7d294a5e),
but the CLI still falls back to checking if this file exists if no current
(`~/.docker/config.json`) file was found.
Given that no version of the CLI since Docker v1.7.0 has created this file,
and if such a file exists, it means someone hasn't re-authenticated for
5 years, it's probably safe to remove this fallback.

Locking was removed in https://github.com/docker/cli/pull/3025 which
allows for parallel calls to config.Load to modify global state.
The consequence in this case is innocuous, but it does trigger a
`DATA RACE` exception when tests run with `-race` option.

This patch adds the `ALL_PROXY` environment variable to the list of
configurable proxy variables, and updates the documentation.

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:

Relates to the deprecation, added in 3c0a167ed5
The docker CLI up until v1.7.0 used the `~/.dockercfg` file to store credentials
after authenticating to a registry (`docker login`). Docker v1.7.0 replaced this
file with a new CLI configuration file, located in `~/.docker/config.json`. When
implementing the new configuration file, the old file (and file-format) was kept
as a fall-back, to assist existing users with migrating to the new file.
Given that the old file format encourages insecure storage of credentials
(credentials are stored unencrypted), and that no version of the CLI since
Docker v1.7.0 has created this file, the file is marked deprecated, and support
for this file will be removed in a future release.
This patch adds a deprecation warning, which is printed if the CLI falls back
to using the deprecated ~/.dockercfg file.

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.

commit c2626a8270 replaced the use of
github.com/docker/docker/pkg/homedir with Golang's os.UserHomeDir().
This change was partially reverted in 7a279af43d
to account for situations where `$HOME` is not set.
In situations where no configuration file is present in `~/.config/`, the CLI
falls back to looking for the (deprecated) `~/.dockercfg` configuration file,
which was still using `os.UserHomeDir()`, which produces an error/warning if
`$HOME` is not set.
This patch introduces a helper function and a global variable to get the user's
home-directory. The global variable is used to prevent repeatedly looking up
the user's information (which, depending on the setup can be a costly operation).

In situations where `~/.docker/config.json` was a symlink, saving
the file would replace the symlink with a file, instead of updating
the target file location;
mkdir -p ~/.docker
touch ~/real-config.json
ln -s ~/real-config.json ~/.docker/config.json
ls -la ~/.docker/config.json
# lrwxrwxrwx 1 root root 22 Jun 23 12:34 /root/.docker/config.json -> /root/real-config.json

Before this change, a warning would be printed if the `~/.docker/config.json`
file was empty:

Given that we also accept an empty "JSON" file (`{}`), it should be
okay to ignore an empty file, as it's effectively a configuration file
with no custom options set.

There's no need to perform an `os.Stat()` first, because
`os.Open()` also returns the same errors if the file does
not exist, or couldn't be opened for other reasons.

When running `docker login` or `docker logout`, the CLI updates
the configuration file by creating a temporary file, to replace
the old one (if exists).
When using `sudo`, this caused the file to be created as `root`,
making it inaccessible to the current user.
This patch updates the CLI to fetch permissions and ownership of
the existing configuration file, and applies those permissions
to the new file, so that it has the same permissions as the
existing file (if any).
Currently, only done for "Unix-y" systems (Mac, Linux), but
can be implemented for Windows in future if there's a need.

Although this should work well enough in traditional environments,
this could break minimal containerized environments.

This PR adds a store to the CLI, that can be leveraged to persist and
retrieve credentials for various API endpoints, as well as
context-specific settings (initially, default stack orchestrator, but we
could expand that).
This comes with the logic to persist and retrieve endpoints configs
for both Docker and Kubernetes APIs.
