Madhu Venugopal c072458308 Make discovery ttl and heartbeat configurable
Docker daemon uses kv-store as the host-discovery backend.
Discovery module tracks the liveness of a node through a simple
keepalive mechanism.  The keepalive mechanism depends on every
node performing heartbeat by registering itself with the discovery
module (via KV-Store Put operation). And for every Put operation,
the discovery module in all other nodes will receive a Watch
notification. That keeps the node alive.
Any node that fails to register itself within the TTL timer is
considered dead and removed from the discovery database.

The default timer (heartbeat = 20 seconds & ttl = 60 seconds)
works fine for small clusters.  But for large clusters, these
default timers are extremely aggressive and that causes high CPU
& most of the processing is spent managing the node discovery
and that impacts normal daemon operation.

Hence we need a way to make the discovery ttl and heartbeat
configurable.  As the cluster size grows, the user can change
these timers to make sure the daemon scales.

NIWA Hideyuki fa2f024bc6 Addition of "--shm-size" to which size of /dev/shm is changed.
- Optional "--shm-size=" was added to the sub-command(run, create,and build).
- The size of /dev/shm in the container can be changed
  when container is made.
- Being able to specify is a numerical value that applies number,
  b, k, m, and g.
- The default value is 64MB, when this option is not set.
- It deals with both native and lxc drivers.

Alexander Morozov 941952972e Use fs cgroups by default
Our implementation of systemd cgroups is mixture of systemd api and
plain filesystem api. It's hard to keep it up to date with systemd and
it already contains some nasty bugs with new versions. Ideally it should
be replaced with some daemon flag which will allow to set parent systemd
slice.

Dan Walsh 212fe5f2d0 Relabel BTRFS Content on container Creation
This change will allow us to run SELinux in a container with
BTRFS back end.  We continue to work on fixing the kernel/BTRFS
but this change will allow SELinux Security separation on BTRFS.

It basically relabels the content on container creation.

Just relabling -init directory in BTRFS use case. Everything looks like it
works. I don't believe tar/achive stores the SELinux labels, so we are good
as far as docker commit.

Tested Speed on startup with BTRFS on top of loopback directory. BTRFS
not on loopback should get even better perfomance on startup time.  The
more inodes inside of the container image will increase the relabel time.

This patch will give people who care more about security the option of
runnin BTRFS with SELinux.  Those who don't want to take the slow down
can disable SELinux either in individual containers or for all containers
by continuing to disable SELinux in the daemon.

Without relabel:

> time docker run --security-opt label:disable fedora echo test
test

real    0m0.918s
user    0m0.009s
sys    0m0.026s

With Relabel
