Allow users to specify the maximum size of a containers in the
/etc/containers/storage.conf file. This will enable quota checking
in the drivers that support it.
Allowe users to OverrideKernelCheck to tell drivers to ignore kernel
version checks that indicate whether the driver is supported on that
kernel. These checks do not make sense on older RHEL kernels, since
the driver support was back ported.

We have a conflict on man pages storage.conf man page is owned
by the inn package, so we need to pick a less generic name.

Add an optional *DiffOptions parameter to Diff() methods (which can be
nil), to allow overriding of default behaviors.
At this time, that's just what type of compression is applied, if we
want something other than what was recorded when the diff was applied,
but we can add more later if needed.

Rename the CLI tool to match the name that we gave the transport that
uses it in containers/image, which affects just about every consumer of
this library.

Container Storage is going to be shared by multiple tools. Therefore
we don't want each one of these tools setting up its own container
storage. This storage config can be shared between multiple users.

Add a method for calling the underlying driver's Cleanup() method,
preferably when it's not going to disrupt another user of the same data
store, and try to give other users of the store a way to notice that the
driver's been cleaned up, so they need to reinitialize things before
continuing to use them.

Add GetContainerDirectory and GetContainerRunDirectory methods to the
store, for getting the location of a directory in which the caller can
manage data directly.
This breaks the general model of keeping the library's caller from
having to bother with where things are stored once the library is
initialized, but is added so that ocid won't have to manage the
directory in which it's dropping files to be picked up by other
binaries, in particular configuration files that it's leaving for runc.

Make sure that the users enable both the socket and service for docker
as part of the default install instructions. If both are not enabled
docker will not start at boot and restart containers.

- the constraint expression needs to be quoted
- add an actual redis container to run so the command line works

Using tabs here seems to cause copy/paste problems in some terminals.
Using spaces is safer.

The change to runc in https://github.com/opencontainers/runc/pull/789
was not documented previously. Also say what this affects and clean
up layout of initial table as there was some miscolouration of the
continuation lines.

The output uses tabs, but those don't
translate well to the rendered output in
the docs, so replacing the tabs with spaces.
Also updates the output, because REPLICATED,
and SPREAD are no longer all-caps in the
actual output.

This adds an `--oom-score-adjust` flag to the daemon so that the value
provided can be set for the docker daemon's process. The default value
for the flag is -500. This will allow the docker daemon to have a
less chance of being killed before containers do. The default value for
processes is 0 with a min/max of -1000/1000.
-500 is a good middle ground because it is less than the default for
most processes and still not -1000 which basically means never kill this
process in an OOM condition on the host machine. The only processes on
my machine that have a score less than -500 are dbus at -900 and sshd
and xfce( my window manager ) at -1000. I don't think docker should be
set lower, by default, than dbus or sshd so that is why I chose -500.
