spotted `DockerContainer` in types.go and pulling on whether we
really needed it found that a bunch of code is not really
required.

As part of this change, the code responsible for managing the sandbox
image within the kubelet has been removed. Previously, the kubelet used
to prevent sandbox image from the garbage collection process. However,
with this update, the responsibility of managing the sandbox containers
has been shifted to the CRI implementation itself. By allowing sandbox
image pinning from CRI, we improve efficiency and simplify the kubelet's
interaction with the container runtime. As a result, the kubelet can now
rely on the container runtime's built-in mechanisms for sandbox container
lifecycle management.

To keep things in sync when adding new traces, we now use the official
semconv types of OTEL rather than our own values.
Nothing should change for now behavior wise.

The two are not coupled except accidentally. Separate them and
update callsites. This will reduce the scope of PodManager interface
to make exposing the pod worker cleaner.
The HandlePod* methods are all structurally similar, but accrued
subtle differences. In general the only point for Handle is to
process admission and to update the pod worker with the desired
state of the kubelet's config (so that pod worker can make it
the actual state).
Add a new GetPodAndMirrorPod() method that handles when the config
pod is ambiguous (pod or mirror pod) and inline the structure.
Add comments on questionable additions in the config methods for
future improvement.
Move the metric observation of container count closer to where
pods are actually started (in the pod worker). A future change
can likely move it to syncPod.
This allows us to return with a timeout error as soon as the
context is canceled. Previously in cases where the mount will
never succeed pods can get stuck deleting for 2 minutes.
In the Sync*Pod methods that call VolumeManager.WaitFor*, we
must filter out wait.Interrupted errors from being logged as
they are part of control flow, not runtime problems. Any
early interruption should result in exiting the Sync*Pod method
as quickly as possible without logging intermediate errors.
on unix, the podresources endpoint is a unix domain socket;
on windows, the podresources endpoint is a named pipe;
rename the variables to convey this fact. No changes in behavior.

To enable rate limiting, needed for GA graduation,
we need to pass more parameters to the already crowded
`ListenAndServePodresources` function.
To tidy up a bit, pack the parameters in a helper struct,
with no intended changes in behavior.
