This modifies the "docker help" text so that it is no wider than 80 chars
and each description fits on one line. This will also try to use ~ when
possible
Added a test to make sure we don't go over 80 chars again.
Added a test to make sure we use ~
Applied rules/tests to all docker commands - not just main help text

We want to be able to use container without the PID namespace. We basically
want containers that can manage the host os, which I call Super Privileged
Containers. We eventually would like to get to the point where the only
namespace we use is the MNT namespace to bring the Apps userspace with it.
By eliminating the PID namespace we can get better communication between the
host and the clients and potentially tools like strace and gdb become easier
to use. We also see tools like libvirtd running within a container telling
systemd to place a VM in a particular cgroup, we need to have communications of the PID.
I don't see us needing to share PID namespaces between containers, since this
is really what docker exec does.
So currently I see us just needing docker run --pid=host

Forbid `docker run -t` with a redirected stdin (such as `echo test |
docker run -ti busybox cat`). Forbid `docker exec -t` with a redirected
stdin. Forbid `docker attach` with a redirect stdin toward a tty enabled
container.

Signal proxy does work only in non-TTY mode (--tty=false). Man pages and

Some workloads rely on IPC for communications with other processes. We
would like to split workloads between two container but still allow them
to communicate though shared IPC.
This patch mimics the --net code to allow --ipc=host to not split off
the IPC Namespace. ipc=container:CONTAINERID to share ipc between containers
If you share IPC between containers, then you need to make sure SELinux labels
match.

security-opts will allow you to customise the security subsystem.
For example the labeling system like SELinux will run on a container.
--security-opt="label:user:USER" : Set the label user for the container
--security-opt="label:role:ROLE" : Set the label role for the container
--security-opt="label:type:TYPE" : Set the label type for the container
--security-opt="label:level:LEVEL" : Set the label level for the container
--security-opt="label:disabled" : Turn off label confinement for the container
Since we are passing a list of string options instead of a space separated
string of options, I will change function calls to use InitLabels instead of
GenLabels. Genlabels interface is Depracated.

This adds a --add-host host:ip flag which appends lines to /etc/hosts. This is needed in places where you want the container to get a different name resolution than it would through DNS. This was submitted before as #5525, closed, and now I am re-opening. It has come up 2 or 3 times in the last couple days.
