This "soft" deprecates the package, but keeps the local uses of the package,
which can make backporting this to release-branches easier (we can
still move all uses in those branches as well though).

This reverts commit 778ac302b2.
(slightly modified, due to changes that were merged after that).
The reverted commit had two elements;
- Make `G` an actual function to improve the documentation
- Prevent `G` from being overwritten externally
From the commit that's reverted:
> The `G` variable is exported, and not expected to be overwritten
> externally. Defining it as a function also documents it as a function
> on https://pkg.go.dev, instead of a variable; https://pkg.go.dev/github.com/containerd/containerd@v1.6.22/log#pkg-variables
While it's unclear if the ability to replace the implementation was
_intentional_, it's this part that some external consumers were (ab)using.
We should look into that part in a follow-up, and design for this, for
example by providing a utility to replace the logger, and properly document
that.
In the meantime, let's revert the change.

Add a package doc to (try to) describe the purpose of this package, and
to describe the purpose (and expectations) of aliases provided by the
package.
> Package log provides types and functions related to logging, passing
> loggers through a context, and attaching context to the logger.
>
> # Transitional types
>
> This package contains various types that are aliases for types in [logrus].
> These aliases are intended for transitioning away from hard-coding logrus
> as logging implementation. Consumers of this package are encouraged to use
> the type-aliases from this package instead of directly using their logrus
> equivalent.
>
> The intent is to replace these aliases with locally defined types and
> interfaces once all consumers are no longer directly importing logrus
> types.
>
> IMPORTANT: due to the transitional purpose of this package, it is not
> guaranteed for the full logrus API to be provided in the future. As
> outlined, these aliases are provided as a step to transition away from
> a specific implementation which, as a result, exposes the full logrus API.
> While no decisions have been made on the ultimate design and interface
> provided by this package, we do not expect carrying "less common" features.

The `G` variable is exported, and not expected to be overwritten
externally. Defining it as a function also documents it as a function
on https://pkg.go.dev, instead of a variable; https://pkg.go.dev/github.com/containerd/containerd@v1.6.22/log#pkg-variables
Note that (while the godoc suggests otherwise) I made `GetLogger` an alias
for `G`, as `G` is the most commonly used function (not the other way round),
although I don't think there's a performance gain in doing so.

While other log-levels are not currently used in containerd itself,
they can be returned by `GetLevel()`, and are accepted (no error) by
`SetLevel()`. We should either accept those values, or produce an
error (in `SetLevel()`), but given that there's other ways to set the
log-level, we should probably acknowledge that this package is a transitional
package, and still closely tied to logrus (for the time being).

This adds valuable logging data to the open telemetry traces.
When the trace is not recording we don't bother doing anything as it is
relatively expensive to convert logrus data to otel just due to the
nature of how logrus works.
The way this works is that we now set a context on the logrus.Entry that
gets passed around which the hook then uses to determine if there is an
active span to forward the logs to.

After comtemplation, the complexity of the logging module system
outweighs its usefulness. This changeset removes the system and restores
lighter weight code paths. As a concession, we can always provide more
context when necessary to log messages to understand them without having
to fork the context for a certain set of calls.

To improve the output of module logging, we now include a path that
represents the modules that a context has passed through. This makes it
easy to tell if a log line came from a particular module hierarchy.
A helper function, `WithModule`, provides an easy way to mark a context
with a module and inject that module into the logger.
