This moves the Attach method from the container to the daemon. This
method mostly supports the http attach logic and does not have anything
to do with the running of a container.

Also make sure we copy the joining containers hosts and resolv.conf with
the hostname if we are joining it's network stack.

Added --selinux-enable switch to daemon to enable SELinux labeling.
The daemon will now generate a new unique random SELinux label when a
container starts, and remove it when the container is removed. The MCS
labels will be stored in the daemon memory. The labels of containers will
be stored in the container.json file.
When the daemon restarts on boot or if done by an admin, it will read all containers json files and reserve the MCS labels.
A potential problem would be conflicts if you setup thousands of containers,
current scheme would handle ~500,000 containers.

This has every container using the docker daemon's pid for the processes
label so it does not work correctly.

container.Kill() might read a pid of 0 from
container.State.Pid due to losing a race with
container.monitor() calling
container.State.SetStopped(). Sending a SIGKILL to
pid 0 is undesirable as "If pid equals 0, then sig
is sent to every process in the process group of
the calling process."
