To allow flexibility in log message context information, this changeset
provides the ability to configure static fields that are included in the
context. Such fields can be set via configuration or environment variables.

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.

This also breaks the dependency the storage package had on goamz

Endpoints are now created at applications startup time, using notification
configuration. The instances are then added to a Broadcaster instance, which
becomes the main event sink for the application. At request time, an event
bridge is configured to listen to repository method calls. The actor and source
of the eventBridge are created from the requeest context and application,
respectively. The result is notifications are dispatched with calls to the
context's Repository instance and are queued to each endpoint via the
broadcaster.
This commit also adds the concept of a RequestID and App.InstanceID. The
request id uniquely identifies each request and the InstanceID uniquely
identifies a run of the registry. These identifiers can be used in the future
to correlate log messages with generated events to support rich debugging.
The fields of the app were slightly reorganized for clarity and a few horrid
util functions have been removed.

If configured, a debug http server will be started to serve default registered
endpoints, such as pprof and expvar. The endpoint should be secured carefully
and not available to external traffic. It is disabled by default but the
development config has been modified to make it available on localhost.

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.

To support clustered registry, upload UUIDs must be recognizable by
registries that did not issue the UUID. By creating an HMAC verifiable
upload state token, registries can validate upload requests that other
instances authorized. The tokenProvider interface could also use a redis
store or other system for token handling in the future.
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.
Most conditional parsing code has been moved into UnmarshalYAML
functions for simplicity
Uses the BrianBland fork of goyaml in configuration.go temporarily until
