Hey,

I've laid some groundwork to which I call 'TrusteDocker' in this branch:

https://github.com/shaded-enmity/docker/blob/trustedv2/engine/trusted/trusted.go

It's supposed to work in the following way:
- docker daemon is started with the --trusted flag, this labels the
process as SELinux type 'docker_daemon_t', daemon also labels the
created Unix socket as 'docker_socket_t'. Define a policy that allows
only docker_daemon_t to talk to docker_socket_t. This ensures that the
daemon communicates only with compatible binary; other methods of
communication with the daemon have to be disabled (TCP).

- each request that is sent from Docker Cli to the daemon is decorated
with 2 additional HTTP headers, UID/EUID of the user.

- Containers can be labeled on per-process basis, but I'm not sure how
to label image files so that users can have private images
(with the v2 image spec this is easy as we can simply label the
manifest, which is what defines the image)

- I'm not sure whether to define a specific label for each user, or just
use the UID aka MCS.
