Importing the `k8s.io/kubernetes/pkg/features` package in the remote
runtime implementation makes it harder to separate the functionalities
at some later point in time.
We now decouple them by checking if the feature is enabled directly in
the kubelet service creation path.

The current error comparison `imagePullResult.err ==
ErrRegistryUnavailable` will never work with any remote runtime, because
we produce gRPC errors which wrap a code and a description, like:
```
rpc error: code = Unknown desc = This is the error description
```
To be able to check custom error types from `pkg/kubelet/images/types.go`,
we now strip the code if the status is unknown on image pull.
Beside that, we use a string comparison to check against
`ErrRegistryUnavailable.Error()`, because validating them via the
`errors` package is not yet supported by grpc-go:

The utils found in pkg/kubelet/cri/remote/utils are the same as the
ones in pkg/kubelet/utils, with the difference that the latter have
had a few improvements recently.
This commit removes the duplicated code.
v1.43.0 marked grpc.WithInsecure() deprecated so this commit moves to use
what is the recommended replacement:
grpc.WithTransportCredentials(insecure.NewCredentials())

The remote runtime implementation now supports the `verbose` fields,
which are required for consumers like cri-tools to enable multi CRI
version support.

This patch makes the CRI `v1` API the new project-wide default version.
To allow backwards compatibility, a fallback to `v1alpha2` has been added
as well. This fallback can either used by automatically determined by
the kubelet.
