7835d261d8 Add generic content digest tool
Previously a useful gist, this changeset polishes the original tarsum tool into
a utility that can be used to calculate content digests. Any algorithm from the
digest package is supported with additional support from tarsum.

This tool is very useful for quickly checking backend digests and verifying
correctness.

74080b7225 Provide yes man endpoint for inflexible load balancers
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.

6ba799b69e Provide simple storage driver health check
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.

Richard Scothern
94935f39bc Add pull through cache functionality to the Registry which can be configured
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.

cache.  Deletion is configurable - if it is disabled API calls
will return an unsupported error.

We invalidate the blob descriptor cache by changing the linkedBlobStore's
blobStatter to a blobDescriptorService and naming it blobAccessController.

Delete() is added throughout the relevant API to support this functionality.

daa22cacba storage/driver/azure: Update vendored Azure SDK
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.

394eea0231 Storage Driver: Ceph Object Storage (RADOS)
This driver implements the storagedriver.StorageDriver interface and
uses Ceph Object Storage as storage backend.

Since RADOS is an object storage and no hierarchy notion, the
following convention is used to keep the filesystem notions stored in
this backend:

* All the objects data are stored with opaque UUID names prefixed
  (e.g. "blob:d3d232ff-ab3a-4046-9ab7-930228d4c164).
* All the hierarchy information are stored in rados omaps, where the
  omap object identifier is the virtual directory name, the keys in
  a specific are the relative filenames and the values the blob
  object identifier (or empty value for a sub directory).

  e.g. For the following hierarchy:

     /directory1
     /directory1/object1
     /directory1/object2
     /directory1/directory2/object3

  The omap "/directory1" will contains the following key / values:
    - "object1" "blob:d3d232ff-ab3a-4046-9ab7-930228d4c164"
    - "object2" "blob:db2e359d-4af0-4bfb-ba1d-d2fd029866a0"
    - "directory2" ""

  The omap "/directory1/directory2" will contains:
    - "object3" "blob:9ae2371c-81fc-4945-80ac-8bf7f566a5d9"

* The MOVE is implemented by changing the reference to a specific
  blob in its parent virtual directory omap.

This driver stripes rados objects to a fixed size (e.g. 4M). The idea
is to keep small objects (as done by RBD on the top of RADOS) that
will be easily synchronized accross OSDs. The information of the
original object (i.e total size of the chunks) is stored as a Xattr
in the first chunk object.

593bbccdb5 Refactor Blob Service API
This PR refactors the blob service API to be oriented around blob descriptors.
Identified by digests, blobs become an abstract entity that can be read and
written using a descriptor as a handle. This allows blobs to take many forms,
such as a ReadSeekCloser or a simple byte buffer, allowing blob oriented
operations to better integrate with blob agnostic APIs (such as the `io`
package). The error definitions are now better organized to reflect conditions
that can only be seen when interacting with the blob API.

The main benefit of this is to separate the much smaller metadata from large
file storage. Many benefits also follow from this. Reading and writing has
been separated into discrete services. Backend implementation is also
simplified, by reducing the amount of metadata that needs to be picked up to
simply serve a read. This also improves cacheability.

"Opening" a blob simply consists of an access check (Stat) and a path
calculation. Caching is greatly simplified and we've made the mapping of
provisional to canonical hashes a first-class concept. BlobDescriptorService
and BlobProvider can be combined in different ways to achieve varying effects.

Recommend Review Approach
-------------------------

This is a very large patch. While apologies are in order, we are getting a
considerable amount of refactoring. Most changes follow from the changes to
the root package (distribution), so start there. From there, the main changes
are in storage. Looking at (*repository).Blobs will help to understand the how
the linkedBlobStore is wired. One can explore the internals within and also
branch out into understanding the changes to the caching layer. Following the
descriptions below will also help to guide you.

To reduce the chances for regressions, it was critical that major changes to
unit tests were avoided. Where possible, they are left untouched and where
not, the spirit is hopefully captured. Pay particular attention to where
behavior may have changed.

Storage
-------

The primary changes to the `storage` package, other than the interface
updates, were to merge the layerstore and blobstore. Blob access is now
layered even further. The first layer, blobStore, exposes a global
`BlobStatter` and `BlobProvider`. Operations here provide a fast path for most
read operations that don't take access control into account. The
`linkedBlobStore` layers on top of the `blobStore`, providing repository-
scoped blob link management in the backend. The `linkedBlobStore` implements
the full `BlobStore` suite, providing access-controlled, repository-local blob
writers. The abstraction between the two is slightly broken in that
`linkedBlobStore` is the only channel under which one can write into the global
blob store. The `linkedBlobStore` also provides flexibility in that it can act
over different link sets depending on configuration. This allows us to use the
same code for signature links, manifest links and blob links.  Eventually, we
will fully consolidate this storage.

The improved cache flow comes from the `linkedBlobStatter` component
of `linkedBlobStore`. Using a `cachedBlobStatter`, these combine together to
provide a simple cache hierarchy that should streamline access checks on read
and write operations, or at least provide a single path to optimize. The
metrics have been changed in a slightly incompatible way since the former
operations, Fetch and Exists, are no longer relevant.

The fileWriter and fileReader have been slightly modified to support the rest
of the changes. The most interesting is the removal of the `Stat` call from
`newFileReader`. This was the source of unnecessary round trips that were only
present to look up the size of the resulting reader. Now, one must simply pass
in the size, requiring the caller to decide whether or not the `Stat` call is
appropriate. In several cases, it turned out the caller already had the size
already. The `WriterAt` implementation has been removed from `fileWriter`,
since it is no longer required for `BlobWriter`, reducing the number of paths
which writes may take.

Cache
-----

Unfortunately, the `cache` package required a near full rewrite. It was pretty
mechanical in that the cache is oriented around the `BlobDescriptorService`
slightly modified to include the ability to set the values for individual
digests. While the implementation is oriented towards caching, it can act as a
primary store. Provisions are in place to have repository local metadata, in
addition to global metadata. Fallback is implemented as a part of the storage
package to maintain this flexibility.

One unfortunate side-effect is that caching is now repository-scoped, rather
than global. This should have little effect on performance but may increase
memory usage.

Handlers
--------

The `handlers` package has been updated to leverage the new API. For the most
part, the changes are superficial or mechanical based on the API changes. This
did expose a bug in the handling of provisional vs canonical digests that was
fixed in the unit tests.

Configuration
-------------

One user-facing change has been made to the configuration and is updated in
the associated documentation. The `layerinfo` cache parameter has been
deprecated by the `blobdescriptor` cache parameter. Both are equivalent and
configuration files should be backward compatible.

Notifications
-------------

Changes the `notification` package are simply to support the interface
changes.

Context
-------

A small change has been made to the tracing log-level. Traces have been moved
from "info" to "debug" level to reduce output when not needed.
