Previously, if while polling for oauth device-code login results a user
suspended the process (such as with CTRL-Z) and then restored it with
`fg`, an error might occur in the form of:
```
failed waiting for authentication: You are polling faster than the specified interval of 5 seconds.
```
This is due to our use of a `time.Ticker` here - if no receiver drains
the ticker channel (and timers/tickers use a buffered channel behind the
scenes), more than one tick will pile up, causing the program to "tick"
twice, in fast succession, after it is resumed.
The new implementation replaces the `time.Ticker` with a `time.Timer`
(`time.Ticker` is just a nice wrapper) and introduces a helper function
`resetTimer` to ensure that before every `select`, the timer is stopped
and it's channel is drained.

Normalization/converting the registry address to just a hostname happens
inside of `command.GetDefaultAuthConfig`. Use this value for the rest of
the login flow/storage.
Signed-off-by: Laura Brehm <laurabrehm@hey.com>
This reverts commit e6624676e0.
Since e6624676e0, during login, we started
normalizing `registry-1.docker.io` to `index.docker.io`. This means that
if a user logs in with `docker login -u [username]
registry-1.docker.io`, the user's credentials get stored in
credhelpers/config.json under `https://index.docker.io/v1/`.
However, while the registry code normalizes an image reference without
registry (`docker pull alpine:latest`) and image references explicitly for
`index.docker.io` (`docker pull index.docker.io/library/alpine:latest`)
to the official index server (`https://index.docker.io/v1/`), and
fetches credentials for that auth key, it does not normalize
`registry-1.docker.io`, which means pulling explicitly from there
(`docker pull registry-1.docker.io/alpine:latest`) will not use
credentials stored under `https://index.docker.io/v1/`.
As such, until changes are made to the registry/pull/push code to
normalize `registry-1.docker.io` to `https://index.docker.io/v1/`, we
should not normalize this during login.

On `docker ps`, port bindings with an IPv6 HostIP should have their
addresses put into brackets when joining them to their ports.
RFC 3986 (Section 3.2.2) stipulates that IPv6 addresses should be
enclosed within square brackets. This RFC is only about URIs. However,
doing so here helps user identifier what's part of the IP address and
what's the port. It also makes it easier to copy/paste that
'[addr]:port' into other software (including browsers).

This commit adds support for the oauth [device-code](https://auth0.com/docs/get-started/authentication-and-authorization-flow/device-authorization-flow)
login flow when authenticating against the official registry.
This is achieved by adding `cli/internal/oauth`, which contains code to manage
interacting with the Docker OAuth tenant (`login.docker.com`), including launching
the device-code flow, refreshing access using the refresh-token, and logging out.
The `OAuthManager` introduced here is also made available through the `command.Cli`
interface method `OAuthManager()`.
In order to maintain compatibility with any clients manually accessing
the credentials through `~/.docker/config.json` or via credential
helpers, the added `OAuthManager` uses the retrieved access token to
automatically generate a PAT with Hub, and store that in the
credentials.

The addSSHTimeout and disablePseudoTerminalAllocation were added in commits
a5ebe2282a and f3c2c26b10,
and called inside the Dialer function, which means they're called every
time the Dialer is called. Given that the sshFlags slice is not mutated
by the Dialer, we can call these functions once.

This test was just incorrect (and testing incorrect
behavior): it was checking that `docker run` exited with a `context
canceled` error after signalling the CLI/cancelling the command's
context, but this was incorrect (and was fixed in
991b1303da - which was when this test
started failing).
However, since this test assertion was happening inside of a goroutine,
it would sometimes pass if this assertion didn't get to run before the
test suite terminated. It was flaky because sometimes this assertion
inside the goroutine did get to execute, but after the test finished
execution, which is a big no-no.
As an aside, assertions inside goroutines are generally bad, and `govet`
even has a linter for this (but it only catches `t.Fatal` and `t.FailNow`
calls and not `assert.Xx`.

Such as with `docker run`, if a user CTRL-Cs while attached to a
container, we should forward the signal and wait for the exit from
`ContainerWait`, instead of just returning.

In 3f0d90a2a9 we introduced a global
signal handler and made sure all the contexts passed into command
execution get (appropriately) cancelled when we get a SIGINT.
Due to that change, and how we use this context during `docker attach`,
we started to return the context cancelation error when a user signals
the running `docker attach`.
Since this is the intended behavior, we shouldn't return an error, so
this commit adds checks to ignore this specific error in this case.
Also adds a regression test.

Looks like this test was failing due to bad syntax on the `while` loop,
which caused it to die after 1 second. If the test took a bit longer,
the process would be dead before the following assertions run, causing
the test to fail/be flaky.

This environment variable allows for setting additional headers
to be sent by the client. Headers set through this environment
variable are added to headers set through the config-file (through
the HttpHeaders field).
This environment variable can be used in situations where headers
must be set for a specific invocation of the CLI, but should not
be set by default, and therefore cannot be set in the config-file.
WARNING: If both config and environment-variable are set, the environment
variable currently overrides all headers set in the configuration file.
This behavior may change in a future update, as we are considering the
environment variable to be appending to existing headers (and to only
override headers with the same name).

The fileStore itself is aware that it's insecure, so we can make it
responsible for printing the warning. It's not "perfect", as we use
`os.Stderr` unconditionally (not `dockerCli.Err()`), but probably won't
make a difference in _most_ cases.

- Add an empty line before the warning to separate it from the command's output
- Use the `/go/` redirect URL that we have available.
- Put quotes around the filename used for storage.
- Use present tense for the message, as the message is printed while saving.
- User "credentials" instead of "password" for consistency with "credentials-store"

If we fail to save credentials, make sure that the error about saving
doesn't get lost in the warning about credentials being stored unencrypted.
Also discard errors about printing the warning, as those would be unlikely,
and if they would occur, probably would fail to be printed as well.

The `reportError` utility was present because cli.StatusError would print
the error decorated with `Status: <error-message>, Code: <exit-code>`.
That was not desirable in many cases as it would mess-up the output. To
prevent this, the CLI had code to check for an empty `Status` (error message)
in which case the error would be "ignored" (and only used for the exit-status),
and the `reportError` utility would be used to manually print a custom error
message before returning the error.
Now that bca2090061 fixed the output format
of `cli.StatusError`, and 3dd6fc365d and
350a0b68a9 no longer discard these error,
we can get rid of this utility, and just set the error-message for
the status-error.
This patch:
- Introduces a `withHelp` which takes care of decorating errors with
a "Run --help" hint for the user.
- Introduces a `toStatusError` utility that detects certain errors in
the container to assign a corresponding exit-code (these error-codes
can be used to distinguish "client" errors from "container" errors).
- Removes the `reportError` utility, and removes code that manually
printed errors before returning.
Behavior is mostly unmodified, with the exception of some slight reformatting
of the errors:
- `withHelp` adds a `docker:` prefix to the error, to indicate the error
is produced by the `docker` command. This prefix was already present
in most cases.
- The "--help" hint is slightly updated ("Run 'docker run --help' for
more information" instead of "See 'docker run --help'"), to make it
more clear that it's a "call to action".
- An empty is added before the "--help" hint to separate it better from
the error-message.
