There is probably a better place for this documentation but we'd like to move
this elsewhere than a github issue. We can move this to a more appropriate
location with the documentation effort.

This allows one to better control the usage of the cache and turn it off
completely. The storage configuration module was modified to allow parameters
to be passed to just the storage implementation, rather than to the driver.

This changeset integrates the layer info cache with the registry webapp and
storage backend. The main benefit is to cache immutable layer meta data,
reducing backend roundtrips. The cache can be configured to use either redis or
an inmemory cache.
This provides massive performance benefits for HEAD http checks on layer blobs
and manifest verification.

This changeset defines the interface for layer info caches. Layer info caches
speed up access to layer meta data accessed in storage driver backends. The
two main operations are tests for repository membership and resolving path and
size information for backend blobs.
Two implementations are available. The main implementation leverages redis to
store layer info. An alternative implementation simply caches layer info in
maps, which should speed up resolution for less sophisticated implementations.

By using a resumable digester and storing the state of upload digests between
subsequent upload chunks, finalizing an upload no longer requires reading back
all of the uploaded data to verify the client's expected digest.

This chnage prevents a crash when moving from a non-existent directory that has
a file as a parent. To prevent this, we simply check that the node is a
directory and throws an error if it is not.

This change adds strong validation for the uuid variable for v2 routes. This is
a minor specification change but is okay since the uuid field is controlled by
the server. The character set is restricted to avoid path traversal, allowing
for alphanumeric values and urlsafe base64 encoding.
This change has no effect on client implementations.

Redis has been integrated with the web application for use with various
services. The configuraiton exposes connection details, timeouts and pool
parameters. Documentation has been updated accordingly.
A few convenience methods have been added to the context package to get loggers
with certain fields, exposing some missing functionality from logrus.

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.

Add a function to examine X-Forward-For and X-Real-Ip headers for
originating IP addresses. Use RemoteAddr for notification request
record and HTTP request context.
This changeset simply adds hooks into the configuration system to support
multiple different kinds of output formats. These formatters are provided by
logrus and include options such as "text" and "json". The configuraiton
documentation has been updated accordingly.
