a903b6a9c8 Fix 19575: Docker events doesn't work with authorization plugin
To support the requirement of blocking the request after the daemon
responded the authorization plugin use a `response recorder` that replay
the response after the flow ends.

This commit adds support for commands that hijack the connection and
flushes data via the http.Flusher interface. This resolves the error
with the event endpoint.

562ec005a6 Remove usage of pkg sockets and tlsconfig.
- Use the ones provided by docker/go-connections, they are a drop in replacement.
- Remove pkg/sockets from docker.
- Keep pkg/tlsconfig because libnetwork still needs it and there is a
  circular dependency issue.

f35a0f3210 pkg: authorization: do not register the same plugin
This patches avoids registering (and calling) the same plugin more than
once. Using an helper map which indexes by name guarantees this and keeps
the order.
The behavior of overriding the same name in a flag is consistent with,
for instance, the `docker run -v /test -v /test` flag which register
the volume just once.
Adds integration tests.

Also removes a somehow duplicate debug statement (leaving only the
second one as it's a loop of plugin's manifest):

ccdb366aa5 Docker authorization plug-in infrastructure enables extending the functionality of the Docker daemon with respect to user authorization. The infrastructure enables registering a set of external authorization plug-in. Each plug-in receives information about the user and the request and decides whether to allow or deny the request. Only in case all plug-ins allow accessing the resource the access is granted.
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.
