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.
