Current default basesize is 10G. Change it to 100G. Reason being that for
some people 10G is turning out to be too small and we don't have capabilities
to grow it dyamically.
This is just overcommitting and no real space is allocated till container
actually writes data. And this is no different then fs based graphdrivers
where virtual size of a container root is unlimited.

Replaced github.com/docker/libcontainer with
github.com/opencontainers/runc/libcontaier.
Also I moved AppArmor profile generation to docker.
Main idea of this update is to fix mounting cgroups inside containers.
After updating docker on CI we can even remove dind.

- Refactor opts.ValidatePath and add an opts.ValidateDevice
ValidePath will now accept : containerPath:mode, hostPath:containerPath:mode
and hostPath:containerPath.
ValidateDevice will have the same behavior as current.
- Refactor opts.ValidateEnv, opts.ParseEnvFile
Environment variables will now be validated with the following
definition :
> Environment variables set by the user must have a name consisting
> solely of alphabetics, numerics, and underscores - the first of
> which must not be numeric.

Memory swappiness option takes 0-100, and helps to tune swappiness
behavior per container.
For example, When a lower value of swappiness is chosen
the container will see minimum major faults. When no value is
specified for memory-swappiness in docker UI, it is inherited from
parent cgroup. (generally 60 unless it is changed).

Libcontainer already supported mount container's own cgroup into
container, with this patch, we can see container's own cgroup info
in container.

This takes the final removal for exec commands in two steps. The first
GC tick will mark the exec commands for removal and then the second tick
will remove the config from the daemon.

This adds an event loop for running a GC cleanup for exec command
references that are on the daemon. These cannot be cleaned up
immediately because processes may need to get the exit status of the
exec command but it should not grow out of bounds. The loop is set to a
default 5 minute interval to perform cleanup.
It should be safe to perform this cleanup because unless the clients are
remembering the exec id of the process they launched they can query for
the status and see that it has exited. If they don't save the exec id
they will have to do an inspect on the container for all exec instances
and anything that is not live inside that container will not be returned
in the container inspect.

This removes the exec config from the container after the command exits
so that dead exec commands are not displayed in the container inspect.
The commands are still kept on the daemon so that when you inspect the
exec command, not the container, you are still able to get it's exit
status.
This also changes the ProcessConfig to a pointer.

The ability to save and verify base device UUID (#13896) introduced a
situation where the initialization would panic when removing the device
returns EBUSY.
Functions `verifyBaseDeviceUUID` and `saveBaseDeviceUUID` now take the
lock on the `DeviceSet`, which solves the problem as `removeDevice`
assumes it owns the lock.
