Since the Docker-Distribution-API-Version header value may contain multiple
space delimited versions as well as many instances of the header key, the
header value is now split on whitespace characters to iterate over all versions
that may be listed in one instance of the header.

This change provides a toolkit for intercepting registry calls, such as
`ManifestService.Get` and `LayerUpload.Finish`, with the goal of easily
supporting interesting callbacks and listeners. The package proxies
returned objects through the decorate function before creation, allowing one to
carefully choose injection points.
Use cases range from notification systems all the way to cache integration.
While such a tool isn't strictly necessary, it reduces the amount of code
required to accomplish such tasks, deferring the tricky aspects to the
decorator package.

v2 ping now checks for a Docker-Distribution-API-Version
header that identifies the endpoint as "registry/2.0"

This speeds up the build (and makes it more consistent) since it doesn't have to clone a bunch of repos. 👍

Setting a header for all responses can help clients better determine
if the server speaks the legacy v1 API or the v2 API. It is important
that the header be set *BEFORE* routing the request.

Fixes#10129
Makes the .dockercfg more human parsable.
Also cleaned up the (technically) racey login test.

In support of making the storage API ready for supporting notifications and
mirroring, we've begun the process of paring down the storage model. The
process started by creating a central Registry interface. From there, the
common name argument on the LayerService and ManifestService was factored into
a Repository interface. The rest of the changes directly follow from this.
An interface wishlist was added, suggesting a direction to take the registry
package that should support the distribution project's future goals. As these
objects move out of the storage package and we implement a Registry backed by
the http client, these design choices will start getting validation.

Token cache prevents the need to get a new token for every registry interaction.
Since the tokens are short lived, the cache expires after only a minute.

While the v2 pull operation is writing the body of the layer blob to disk
it now computes the tarsum checksum of the archive before extracting it to
the backend storage driver. If the checksum does not match that from the
image manifest an error is raised.
Also adds more debug logging to the pull operation and fixes existing test
cases which were failing. Adds a reverse lookup constructor to the tarsum
package so that you can get a tarsum object using a checksum label.
