It will Tar up contents of child directory onto tmpfs if mounted over
This patch will use the new PreMount and PostMount hooks to "tar"
up the contents of the base image on top of tmpfs mount points.

Closes#9798
@maintainers please note that this is a change to the UX. We no longer
require the -f flag on `docker tag` to move a tag from an existing image.
However, this does make us more consistent across our commands,
see https://github.com/docker/docker/issues/9798 for the history.

ext4 filesystem creation can take a long time on 100G thin device and
systemd might time out and kill docker service. Often user is left thinking
why docker is taking so long and logs don't give any hint. Log an info
message in journal for start and end of filesystem creation. That way
a user can look at logs and figure out that filesystem creation is
taking long time.

libcontainer v0.0.4 introduces setting `/proc/self/oom_score_adj` to
better tune oom killing preferences for container process. This patch
simply integrates OomScoreAdj libcontainer's config option and adjust

Currently, the resources associated with the io.Reader returned by
TarStream are only freed when it is read until EOF. This means that
partial uploads or exports (for example, in the case of a full disk or
severed connection) can leak a goroutine and open file. This commit
changes TarStream to return an io.ReadCloser. Resources are freed when
Close is called.

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.

This is a small configuration struct used in two scenarios:
1. To attach I/O pipes to a running containers.
2. To attach to execution processes inside running containers.
Although they are similar, keeping the struct in the same package
than exec and container can generate cycled dependencies if we
move any of them outside the daemon, like we want to do
with the container.

- 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.
