The v2 registry will act as a pull-through cache, and needs to be
handled differently by the client to the v1 registry mirror.
See docker/distribution#459 for details
Configuration
Only one v2 registry can be configured as a mirror. Acceptable configurations
in this chanage are: 0...n v1 mirrors or 1 v2 mirror. A mixture of v1 and v2
mirrors is considered an error.
Pull
If a v2 mirror is configured, all pulls are redirected to that mirror. The
mirror will serve the content locally or attempt a pull from the upstream mirror,
cache it locally, and then serve to the client.
Push
If an image is tagged to a mirror, it will be pushed to the mirror and be
stored locally there. Otherwise, images are pushed to the hub. This is
unchanged behavior.

This patch removes the need for requestFactories and decorators
by implementing http.RoundTripper transports instead.
It refactors some challenging-to-read code.
NewSession now takes an *http.Client that can already have a
custom Transport, it will add its own auth transport by wrapping
it.
The idea is that callers of http.Client should not bother
setting custom headers for every handler but instead it should
be transparent to the callers of a same context.
This patch is needed for future refactorings of registry,
namely refactoring of the v1 client code.

The intention of the user is to download a verified image if explicitly
pulling with a digest and falling back to v1 registry circumvents that
protection.

This makes `registry.Service` a first class type and does not use jobs
to interact with this type.

Update registry package to use the v2 registry api from distribution. Update interfaces to directly take in digests.

This patch causes `The image you are pulling has been verified` status
message to be produced also when the repository is pulled for the first
time.

When pushing to the official registry, v2 push will be attempted first. If the v2 endpoint is unavailable, a push to v1 will occur. If a v2 push is started and failed, the push operation will fail. Pulling non-official images the official v2 registry is also enabled to pull the newly push images. When a pull of a v2 image fails, v1 will always be attempted.

Add ability to refer to an image by repository name and digest using the
format repository@digest. Works for pull, push, run, build, and rmi.

Update pull code to consider any layer download or new tag as an update.
Update hello-world frozen image to be explicitly tagged as frozen, to not interfere with pull tests. The hello-world is used by pull tests because of its small size and there is no other official image with such a size.

The call to io.Copy was not being checked for errors at a critical point in the
pull logic. This patch will log the error value if not nil.

The trust graph currently pulls the keys needed to verify official images. For non-official images this graph check is useless. To avoid hitting the key statement url when pulling from private v2 registries, restrict the check to official image pulls.

Only show the verification message if all the tarsum checks pass and the image manifest is verified.
No longer return an error when a tarsum verification fails, just reset the verification flag.
Tarsum verification is less meaningful without a verified manifest and therefore it should not cause an error.
Updated the verified image test to pull an image which expected to have a verified manifest and contents.

It didn't work on v2 anyways. And an image with a lot of aliases was slow to
fetch.

On pull treat an unavailable v2 registry as a non-error fallback.
On push only show v2 error message in debug mode.

No longer push to the official v2 registry when it is available. This allows pulling images from the v2 registry without defaulting push. Only pull official images from the v2 official registry.
