if a context is set (e.g. through DOCKER_CONTEXT or the CLI config file), but
wasn't found, then a "stub" context is added, including an error message that
the context doesn't exist.

This updates `docker context ls` to:
- not abort listing contexts when failing one (or more) contexts
- instead, adding an ERROR column to inform the user there was
an issue loading the context.

This allows commands that don't require a client connection (such as `context use`)
to be functional, but still produces an error when trying to run a command that
needs to connect with the API;
mkdir -p ~/.docker/ && echo '{"currentContext":"nosuchcontext"}' > ~/.docker/config.json

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.

This internalizes constructing the Client(), which allows us to provide
fallbacks when trying to determin the current API version.

On termios platforms, interrupt signals are not generated in raw mode terminals
as the ISIG setting is not enabled. Remove interrupt handler as it does nothing
for raw mode and prevents other uses of INT signal with this library.
This code seems to go back all the way to moby/moby#214 where signal handling was
improved for monolithic docker repository. Raw mode -ISIG got reintroduced in
https://github.com/moby/moby/commit/3f63b878076, but the INT handler was left
behind.

As a stepping-stone towards switching to go modules, we're switching the
versioning scheme to be SemVer(ish) instead of CalVer. Note that this
currently still is `+incompatible` version, as changing to a version > 1
requires the module to be renamed, but changes in that area will arrive
in a future release.

Also move the resolveContextName() function together with the
method for easier cross-referencing.

There's no strict need to perform this validation inside this function;
validating flags should happen earlier, to allow faster detecting of
configuration issues (we may want to have a central config "validate"
function though).

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).

Manually updating the indirect dependency to force go.etcd.io/etcd/server/v3
to v3.5.5 or up, which is now compatible with go.opentelemetry.io/otel v1.0.0.
With this, we can remove the replace rule for this module.

no significant changes in vendored code, other than updating build-tags
for go1.17, but removes some dependencies from the module, which can
