On Windows, ignore all variables that start with "=" when building an
environment variables map for stack.
For MS-DOS compatibility cmd.exe can set some special environment
variables that start with a "=" characters, which breaks the general
assumption that the first encountered "=" separates a variable name from
variable value and causes trouble when parsing.
These variables don't seem to be documented anywhere, but they are
described by some third-party sources and confirmed empirically on my
Windows installation.
Useful sources:
https://devblogs.microsoft.com/oldnewthing/20100506-00/?p=14133https://ss64.com/nt/syntax-variables.html
Known variables:
- `=ExitCode` stores the exit code returned by external command (in hex
format)
- `=ExitCodeAscii` - same as above, except the value is the ASCII
representation of the code (so exit code 65 (0x41) becomes 'A').
- `=::=::\` and friends - store drive specific working directory.
There is one env variable for each separate drive letter that was
accessed in the shell session and stores the working directory for that
specific drive.
The general format for these is:
`=<DRIVE_LETTER>:=<CWD>` (key=`=<DRIVE_LETTER>:`, value=`<CWD>`)
where <CWD> is a working directory for the drive that is assigned to
the letter <DRIVE_LETTER>
A couple of examples:
`=C:=C:\some\dir` (key: `=C:`, value: `C:\some\dir`)
`=D:=D:\some\other\dir` (key: `=C:`, value: `C:\some\dir`)
`=Z:=Z:\` (key: `=Z:`, value: `Z:\`)
`=::=::\` is the one that seems to be always set and I'm not exactly
sure what this one is for (what's drive `::`?). Others are set as
soon as you CD to a path on some drive. Considering that you start a
cmd.exe also has some working directory, there are 2 of these on start.
All these variables can be safely ignored because they can't be
deliberately set by the user, their meaning is only relevant to the
cmd.exe session and they're all are related to the MS-DOS/Batch feature
that are irrelevant for us.

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:

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.
