Each plug-in operates as a separate service, and registers with Docker
through general (plug-ins API)
[https://blog.docker.com/2015/06/extending-docker-with-plugins/]. No
Docker daemon recompilation is required in order to add / remove an
authentication plug-in. Each plug-in is notified twice for each
operation: 1) before the operation is performed and, 2) before the
response is returned to the client. The plug-ins can modify the response
that is returned to the client.
The authorization depends on the authorization effort that takes place
in parallel [https://github.com/docker/docker/issues/13697].
This is the official issue of the authorization effort:
https://github.com/docker/docker/issues/14674
(Here)[https://github.com/rhatdan/docker-rbac] you can find an open
document that discusses a default RBAC plug-in for Docker.

A TopicFunc is an interface to let the pubisher decide whether it needs
to send a message to a subscriber or not. It returns true if the
publisher must send the message and false otherwise.
Users of the pubsub package can create a subscriber with a topic
function by calling `pubsub.SubscribeTopic`.
Message delivery has also been modified to use concurrent channels per
subscriber. That way, topic verification and message delivery is not
o(N+M) anymore, based on the number of subscribers and topic verification
complexity.
Using pubsub topics, the API stops controlling the message delivery,
delegating that function to a topic generated with the filtering
provided by the user. The publisher sends every message to the
subscriber if there is no filter, but the api doesn't have to select
messages to return anymore.

Improves the current filtering implementation complixity.

By adding a (*WriteFlusher).Close, we limit the Write calls to possibly
deallocated http response buffers to the lifetime of an http request.
Typically, this is seen as a very confusing panic, the cause is usually a
situation where an http.ResponseWriter is held after request completion. We
avoid the panic by disallowing further writes to the response writer after the
request is completed.

DumpRequest would be called on each request requardless of logging

This patch creates interfaces in builder/ for building Docker images.
It is a first step in a series of patches to remove the daemon
dependency on builder and later allow a client-side Dockerfile builder
as well as potential builder plugins.
It is needed because we cannot remove the /build API endpoint, so we
need to keep the server-side Dockerfile builder, but we also want to
reuse the same Dockerfile parser and evaluator for both server-side and
client-side.
builder/dockerfile/ and api/server/builder.go contain implementations
of those interfaces as a refactoring of the current code.

Although having a request ID available throughout the codebase is very

Use `pkg/discovery` to provide nodes discovery between daemon instances.
The functionality is driven by two different command-line flags: the
experimental `--cluster-store` (previously `--kv-store`) and
`--cluster-advertise`. It can be used in two ways by interested
components:
1. Externally by calling the `/info` API and examining the cluster store
field. The `pkg/discovery` package can then be used to hit the same
endpoint and watch for appearing or disappearing nodes. That is the
method that will for example be used by Swarm.
2. Internally by using the `Daemon.discoveryWatcher` instance. That is
the method that will for example be used by libnetwork.

Avoid creating a global context object that will be used while the daemon is running.
Not only this object won't ever be garbage collected, but it won't ever be used for anything else than creating other contexts in each request. I think it's a bad practive to have something like this sprawling aroud the code.
This change removes that global object and initializes a context in the cases we don't have already one, like shutting down the server.
This also removes a bunch of context arguments from functions that did nothing with it.

This PR adds a "request ID" to each event generated, the 'docker events'
stream now looks like this:
```
2015-09-10T15:02:50.000000000-07:00 [reqid: c01e3534ddca] de7c5d4ca927253cf4e978ee9c4545161e406e9b5a14617efb52c658b249174a: (from ubuntu) create
```
Note the `[reqID: c01e3534ddca]` part, that's new.
Each HTTP request will generate its own unique ID. So, if you do a
`docker build` you'll see a series of events all with the same reqID.
This allow for log processing tools to determine which events are all related
to the same http request.
I didn't propigate the context to all possible funcs in the daemon,
I decided to just do the ones that needed it in order to get the reqID
into the events. I'd like to have people review this direction first, and
if we're ok with it then I'll make sure we're consistent about when
we pass around the context - IOW, make sure that all funcs at the same level
have a context passed in even if they don't call the log funcs - this will
ensure we're consistent w/o passing it around for all calls unnecessarily.
