config.Load() remove unneeded locks
These were added in b83bc67136, but
I'm not sure why I added these; they're likely not needed.

config: print deprecation warning when falling back to ~/.dockercfg
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.

cli/config: prevent warning if HOME is not set
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).

config: remove redundant os.Stat()
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.

config: don't call homedir on init()
This patch changes the package to lazily obtain the user's home-

Tibor Vass 7a279af43d config: revert to using pkg/homedir
In c2626a82 homedir logic got extremely simplified to only
checking HOME environment variable on UNIX systems.

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

This patch reverts to using github.com/docker/docker/pkg/homedir
that was recently updated to have less dependencies.

Simon Ferquel b34f340346 Introduce docker context store
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.
