The "docker context show" command is intended to show the currently configured
context. While the context that's configured may not be valid (e.g., in case
an environment variable was set to configure the context, or if the context
was removed from the filesystem), we should still be able to _show_ the
context.
This patch removes the context validation, and instead only shows the context.
This can help in cases where the context is used to (e.g.) set the command-
prompt, but the user removed the context. With this change, the context name
can still be shown, but commands that _require_ the context will still fail.

resolveContextName() is used to find which context to use, based on the
available configuration options. Once resolved, the context name is
used to load the actual context, which will fail if the context doesn't
exist, so there's no need to produce an error at this stage; only
check priority of the configuration options to pick the context
with the highest priority.

CommonOptions was inherited from when the cli and daemon were in the same
repository, and some options would be shared between them. That's no longer
the case, and some options are even "incorrect" (for example, while the
daemon can be configured to run on multiple hosts, the CLI can only connect
with a single host / connection). This patch does not (yet) address that,
but merges the CommonOptions into the ClientOptions.
An alias is created for the old type, although it doesn't appear there's
any external consumers using the CommonOptions type (or its constructor).

When marshaling the type with `gopkg.in/yaml.v3`, unmarshaling would
recursively call the type's `MarshalYAML()` function, which ultimately
resulted in a crash:
runtime: goroutine stack exceeds 1000000000-byte limit
runtime: sp=0x140202e0430 stack=[0x140202e0000, 0x140402e0000]
fatal error: stack overflow
This applies a similar fix as was implemented in e7788d6f9a
for the `MarshalJSON()` implementation. An alternative would be to use
a type alias (to remove the `MarshalYAML()`), but keeping it simple.

The version was originally added in 570ee9cb54,
at the time the `expected` config did not have a `version:` field. A later
refactor in 0cf2e6353a updated the `expected`
config to have a `version:` included. However, the test was not updated,
which now resulted in the test using a compose file with a duplicate version
field:
version: '3.10'
version: "3.10"
services:
foo:
build:
This issue was masked by `yaml.Unmarshal()` from `gopkg.in/yaml.v2` which
silently ignores the duplicate, taking the value of the last occurrence. When
upgrading to `gopkg.in/yaml.v3`, the duplicate value resulted in an error:
yaml: unmarshal errors:

constructor to return a concrete type.
Signed-off-by: Sebastiaan van Stijn <github@gone.nl>
The package defined various special errors; these errors existed for two reasons;
- being able to distinguish "not found" errors from other errors (as "not found"
errors can be ignored in various cases).
- to be able to update the context _name_ in the error message after the error
was created. This was needed in cases where the name was not available at the
location where the error was produced (e.g. only the "id" was present), and
the helpers to detect "not found" errors did not support wrapped errors (so
wrapping the error with a "name" could break logic); a `setContextName` interface
and corresponding `patchErrContextName()` utility was created for this (which
was a "creative", but not very standard approach).
This patch:
- Removes the special error-types, replacing them with errdefs definitions (which
is a more common approach in our code-base to detect error types / classes).
- Removes the internal utilities for error-handling, and deprecates the exported
utilities (to allow external consumers to adjust their code).
- Some errors have been enriched with detailed information (which may be useful
for debugging / problem solving).
- Note that in some cases, `patchErrContextName()` was called, but the code
producing the error would never return a `setContextName` error, so would
never update the error message.

Before this change, running `docker context rm --force` would fail if the context
did not exist. This behavior was different from other commands, which allowed
ignoring non-existing objects.
For example; when trying to remove a non-existing volume, the command would
fail without "force":
```bash
docker volume rm nosuchvolume
Error: No such volume: nosuchvolume
echo $?
1
```
But using the `-f` / `--force` option would make the command complete successfully
(the error itself is still printed for informational purposes);
```bash
docker volume rm -f nosuchvolume
nosuchvolume
echo $?
0
```
With this patch, `docker context rm` behaves the same:
```bash
docker context rm nosuchcontext
context "nosuchcontext" does not exist
echo $?
1
```
```bash
docker context rm -f nosuchcontext
nosuchcontext
echo $?
0
```
This patch also simplifies how we check if the context exists; previously we
would try to read the context's metadata; this could fail if a context was
corrupted, or if an empty directory was present. This patch now only checks
if the directory exists, without first validating the context's data.

`NewDockerCli` was configuring the standard streams using local code; this patch
instead uses the available `WithStandardStreams()` option to do the same.
There is slight difference in the order of events;
Previously, user-provided options would be applied first, after which NewDockerCli
would check if any of "in", "out", or "err" were nil, and if so set them to the
default stream (or writer) for that output.
The new code unconditionally sets the defaults _before_ applying user-provided
options. In practive, howver, this makes no difference; the fields set are not
exported, and the only functions updating them are `WithStandardStreams`,
`WithInputStream`, and `WithCombinedStream`, neither of which checks the old
value (so always overrides).

Cobra allows for aliases to be defined for a command, but only allows these
to be defined at the same level (for example, `docker image ls` as alias for
`docker image list`). Our CLI has some commands that are available both as a
top-level shorthand as well as `docker <object> <verb>` subcommands. For example,
`docker ps` is a shorthand for `docker container ps` / `docker container ls`.
This patch introduces a custom "aliases" annotation that can be used to print
all available aliases for a command. While this requires these aliases to be
defined manually, in practice the list of aliases rarely changes, so maintenance
should be minimal.
As a convention, we could consider the first command in this list to be the
canonical command, so that we can use this information to add redirects in
our documentation in future.

The default output for Cobra aliases only shows the subcommand as alias, which
is not very intuitive. This patch changes the output to print the full command
as it would be called by the user.
Note that there's still some improvements to be made; due to how aliases must be
set-up in Cobra, aliases at different "levels" are still not shown. So for example,
`docker ps --help` will not show `docker container ps` as alias, and vice-versa.
This will require additional changes, and can possibly be resolved using custom
metadata/annotations.
