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.

Since the containers can handle the out of memory kernel kills gracefully, docker
will only provide out of memory information as an additional metadata as part of
container status.

Lxc driver was throwing errors for mounts where the mount point does not exist in the container.
This adds a create=dir/file mount option to the lxc template, to alleviate this issue.

We removed the syncpipe package and replaced it with specific calls to
create a new *os.File from a specified fd passed to the process. This
reduced code and an extra object to manage the container's init
lifecycle.

Right now, MAC addresses are randomly generated by the kernel when
creating the veth interfaces.
This causes different issues related to ARP, such as #4581, #5737 and #8269.
This change adds support for consistent MAC addresses, guaranteeing that
an IP address will always end up with the same MAC address, no matter
what.
Since IP addresses are already guaranteed to be unique by the
IPAllocator, MAC addresses will inherit this property as well for free.
Consistent mac addresses is also a requirement for stable networking (#8297)
since re-using the same IP address on a different MAC address triggers the ARP
issue.
Finally, this change makes the MAC address accessible through docker
inspect, which fixes#4033.

Add --security-opts options to allow user to customize container labels and apparmor profile
Upstream-commit: d40ab6f1238c78ea84645e516f1f24d7991798b0

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.

commit 4aa5da278f49c889d43191f82ff42d3a95266d62 moves `Console` from Command to
ProcessConfig, but missed the change in lxc_template. Therefore creating a
container with tty using lxc driver with fail with error
template: lxc:60:20: executing "lxc" at <.Console>: Console is not a field of
struct type struct { *execdriver.Command; AppArmor bool; ProcessLabel string; MountLabel string }
This changes lxc_console template to refers to `.ProcessConfig.Console`

This changes the way the exec drivers work by not specifing a -driver
flag on reexec. For each of the exec drivers they register their own
functions that will be matched aginst the argv 0 on exec and called if
they match.
This also allows any functionality to be added to docker so that the
binary can be reexec'd and any type of function can be called. I moved
the flag parsing on docker exec to the specific initializers so that the
implementations do not bleed into one another. This also allows for
more flexability within reexec initializers to specify their own flags
and options.
