the digest cli does not work if we do not import this two packages,
tested in go1.9. basically, we have to make several algorithms to
be available by calling crypto.RegisterHash in init functions.

The current registry/client sends the registered manifest types in
random order. Allow clients to request a single specific manifest type
or a preferred order as per the HTTP spec.

As the `--label` option is used before in `docker node update --label-add registry=true node1`, the Docker registry should be restricted to only run on `node1` - and nowhere else. So the `docker service create` command has to use the option `--constraint 'node.labels.registry==true` instead of `--label registry=true`- because it is a contraint, where to run the Registry - we don´t just want to set a label again.
A statically hosted registry that responds correctly to GET with a
manifest will load the right digest (by looking at the manifest body and
calculating the digest). If the registry returns a HEAD without
`Docker-Content-Digest`, then the client Tags().Get() call will return
an empty digest.
This commit changes the client to fallback to loading the tag via GET if
the `Docker-Content-Digest` header is not set.

AuthorizeRequest() injects the 'pull' scope if `from` is set
unconditionally. If the current token already has that scope, it will
be inserted into the scope list twice and `addedScopes` will be set to
true, resulting in a new token being fetched that has no net new scopes.
Instead, check whether `additionalScopes` are actually new.

To simplify the vendoring story for the client, we have now removed the
requirement for `logrus` and the forked `context` package (usually
imported as `dcontext`). We inject the logger via the metrics tracker
for the blob cache and via options on the token handler. We preserve
logs on the proxy cache for that case. Clients expecting these log
messages may need to be updated accordingly.

Back in the before time, the best practices surrounding usage of Context
weren't quite worked out. We defined our own type to make usage easier.
As this packaged was used elsewhere, it make it more and more
challenging to integrate with the forked `Context` type. Now that it is
available in the standard library, we can just use that one directly.
To make usage more consistent, we now use `dcontext` when referring to
the distribution context package.
