The storage library uses github.com/pkg/errors to wrap errors that it
returns from many of its functions, so when passing them to
os.IsNotExist() or comparing them to specific errors defined in the
storage library, unwrap them using errors.Cause().

Miloslav informs me that the docker transport talking to an OpenShift
registry will handle signatures properly, so no need for the atomic transport
any longer. We want to stop documenting it.

Remove the non-OCI version of the configuration structure, and the
parent image ID, from the ImageData that libkpod returns.
At runtime, cri-o is only ever going to use the OCI configuration
(possibly converted from another format by the image library) when
setting up a container, so it can be confusing to display settings in
"kpod inspect" that might be discarded when we try to run a container.
Remove the non-OCI version of the configuration structure, and the
hard-coded Type field, from the ContainerData that libkpod returns.

We already parse every image if there's a label filter so that we can
check against the filter, so when we do that, go ahead and read the
OCI-format configuration and inspection data as well, and use an image's
creation date as recorded in inspection data everywhere.

Make getStore() take a config struct from which it pulls the store
options, then update the kpod commands so that they call getConfig()
and pass the config into getStore()

This update allows the creation of docker-archive files when the
destination does not exists or is empty. kpod save needs this functionality.

Avoid parsing metadata that the image library keeps in order to find an
image's top layer and creation date; instead, use the values which the
storage library now makes available, which will be correct once we merge
PR #654 or something like it.
Instead of assuming the last blob which was added for the image was the
manifest, read it directly and compute its digest ourselves.

github.com/containers/image.FromUnparsedImage() "takes ownership" of the
UnparsedImage that we pass to it, so we shouldn't also Close() the
UnparsedImage ourselves after we've wrapped it up in an Image object.
Since creating an Image is the only thing we do with the UnparsedImage
after creating it from a SourceImage, just use the FromSource() function
to handle both steps at once.

Don't bother trying to find and parse the image's configuration blob
after we've already done it; just reuse the value. This frees us from
making the assumption that the last blob which was committed to local
storage was the image's configuration blob.

Parse the set of image names as tagged references, canonical references,
or repository names to which we add the default tag, and return them in
libkpod.ImageData reports.

Switch from using the lower-level storage APIs (accessing LayerStore,
ImageStore, and ContainerStore types directly) in favor of the
higher-level ones that take care of synchronization and locking for us.
