Certain load balancers, such as Amazon's Elastic Load Balancer, have a very
limited notion of health. While a properly configured and operational registry
should always return a 401 when hitting "/v2/", such load balancers cannot be
configured to treat this response code as healthy. This changeset makes "/"
always return a 200 response, unless the health checks have failed.

To ensure the ensure the web application is properly operating, we've added a
periodic health check for the storage driver. If the health check fails three
times in a row, the registry will serve 503 response status for any request
until the condition is resolved. The condition is reported in the response body
and via the /debug/health endpoint.
To ensure that all drivers will properly operate with this health check, a
function has been added to the driver testsuite.

with a new `proxy` section in the configuration file.
Create a new registry type which delegates storage to a proxyBlobStore
and proxyManifestStore. These stores will pull through data if not present
locally. proxyBlobStore takes care not to write duplicate data to disk.
Add a scheduler to cleanup expired content. The scheduler runs as a background
goroutine. When a blob or manifest is pulled through from the remote registry,
an entry is added to the scheduler with a TTL. When the TTL expires the
scheduler calls a pre-specified function to remove the fetched resource.
Add token authentication to the registry middleware. Get a token at startup
and preload the credential store with the username and password supplied in the
config file.
Allow resumable digest functionality to be disabled at runtime and disable
it when the registry is a pull through cache.

Change the minimum TLS version to TLS 1.0, and add a custom list of

This change refreshes the updated version of Azure SDK
for Go that has the latest changes.
I manually vendored the new SDK (github.com/Azure/azure-sdk-for-go)
and I removed `management/` `core/` packages manually simply because
they're not used here and they have a fork of `net/http` and `crypto/tls`
for a particular reason. It was introducing a 44k SLOC change otherwise...
This also undoes the `include_azure` flag (actually Steven removed the
driver from imports but forgot to add the build flag apparently, so the
flag wasn't really including azure. 😄 ). This also must be obsolete
now.
Fixes#620, #175.

Allow to use a unix socket as a listener.
To specify an endpoint type we use an optional configuration
field 'net', as there's no way to distinguish a relative
socket path from a hostname.

This moves the instance id out of the app so that it is associated with an
instantiation of the runtime. The instance id is stored on the background
context. This allows allow contexts using the main background context to
include an instance id for log messages. It also simplifies the application
slightly.

You shouldn't have to import both:
github.com/docker/distribution/context
golang.org/x/net/context
just to use the distribution tools and implement the distribution interfaces.
By pulling the Context interface from golang.org/x/net/context into the
context package within the distribution project, you no longer have to import
both packages.
Note: You do not have to change anything anywhere else yet! All current uses
of both packages together will still work correctly because the Context
interface from either package is identical.
I've also made some other minor changes:
- Added a RemoteIP function. It's like RemoteAddr but discards the port suffix
- Added `.String()` to the response duration context value so that JSON log
formatting shows human-parseable duration and not just number of nano-seconds
- Added WithMapContext(...) to the context package. This is a useful function
so I pulled it out of the main.go in cmd/registry so that it can be used
elsewhere.

This change is slightly more complex than previous package maves in that the
package name changed. To address this, we simply always reference the package
driver as storagedriver to avoid compatbility issues with existing code. While
unfortunate, this can be cleaned up over time.

The goal is to free up the distribution/registry package to include common

This changeset integrates contextual logging into the registry web application.
Idiomatic context use is attempted within the current webapp layout. The
functionality is centered around making lifecycle objects (application and
request context) into contexts themselves. Relevant data has been moved into
the context where appropriate. We still have some work to do to factor out the
registry.Context object and the dispatching functionality to remove some
awkward portions.
The api tests were slightly refactored to use a test environment to eliminate
common code.

If configured, a debug http server will be started to serve default registered

This changeset provides simple tls support for a registry instance. Simply
providing a cert and key file are enough to get a tls registry running. If the
certs are trusted by the client, tls can be used throughout the push and pull
process.
If more complex TLS options are required, it is recommend that a proxy be used.
Contributions will be accepted to add more features, if necessary.

We've added support to the registry command to report the current version of
the distribution package. The version package is generated with a shell script
that gets the latest tag and add "+unknown". This allows builds from "go get"
and "go install" to have a rough version number. Generated periodically, it
will provide a decent indication of what code built the binary. For more
accurate versioning, one can build with the "binaries" make target. Linker
flags are used to replace the version string with the actual current tag at
build time.

Since the repo is no longer just the registry, we are moving the registry web
application package out of the repo root into a sub-package. We may break down
the registry package further to separate webapp components and bring the client
package under it. This change accomplishes the task of freeing up the repo root
for a distribution-oriented package. A stub doc.go file is left in place to
declare intent.

This changeset integrates the AccessController into the main registry app. This
includes support for configuration and a test implementation, called "silly"
auth. Auth is only enabled if the configuration is present but takes measure to
ensure that configuration errors don't allow the appserver to start with open
access.
