If platform supports xfs filesystem then use xfs as default filesystem
for container rootfs instead of ext4. Reason being that ext4 is pre-allcating
lot of metadata (around 1.8GB on 100G thin volume) and that can take long
enough on AWS storage that systemd times out and docker fails to start.
If one disables pre-allocation of ext4 metadata, then it will be allocated
when containers are mounted and we will have multiple copies of metadata
per container. For a 100G thin device, it was around 1.5GB of metadata
per container.
ext4 has an optimization to skip zeroing if discards are issued and
underlying device guarantees that zero will be returned when discarded
blocks are read back. devicemapper thin devices don't offer that guarantee
so ext4 optimization does not kick in. In fact given discards are optional
and can be dropped on the floor if need be, it looks like it might not be
possible to guarantee that all the blocks got discarded and if read back
zero will be returned.

If user wants to use a filesystem it can be specified using dm.fs=<filesystem>
option. It is possible that docker already had base image and a filesystem
on that. Later if user wants to change file system using dm.fs= option
and restarts docker, that's not possible. Warn user about it.

With the changes merged into runc/libcontainer, are now causing
SELinux to attempt a relabel always, even if the user did not
request the relabel.
If the user does not specify Z or z on the volume mount we should
not attempt a relabel.

So we don't print those <no value> in the client and we don't fail
executing inspect templates with API field names.
Make sure those fields are initialized as empty slices when
a container is loaded from disk and their values are nil.

This patch adds the ability to run `docker stats` w/o arguments and get
statistics for all running containers by default. Also add a new
`--all` flag to list statistics for all containers (like `docker ps`).
New running containers are added to the list as they show up also.
Add integration tests for this new behavior.
Docs updated accordingly. Fix missing stuff in man/commandline
reference for `docker stats`.
