Some workloads rely on IPC for communications with other processes. We
would like to split workloads between two container but still allow them
to communicate though shared IPC.
This patch mimics the --net code to allow --ipc=host to not split off
the IPC Namespace. ipc=container:CONTAINERID to share ipc between containers
If you share IPC between containers, then you need to make sure SELinux labels
match.

Took care of some review comments from crosbymichael.
v2:
- Return "err = nil" if file deviceset-metadata file does not exist.
- Use json.Decoder() interface for loading deviceset metadata.
v3:
- Reverted back to json marshal interface in loadDeviceSetMetaData().

I noticed a few things that were bugging me in the output
of the integration-cli tests.
- one of the tests used println to stdout so we had garage sent to the screen
- some of the test, in their final log message, didn't include the name of
the group/file e.g. daemon - run,iptables was just run,iptables
And yes, I noticed this because I'm anal :-) but also because we should keep
the output of the tests as clean as possible so its easy to spot it when
things go bad.

This passed the --net=container:CONTINER_ID to lxc-start as --share-net

Current implementation is hard to reason about because of trying to mix
unix/tcp server implementations, even though they are quite different.
This cleans that up.
Also makes it possible to create and manage a new API server easily,
e.g. for adding an introspection socket to a container.
Built in such a way as to allow a non-HTTP server to work as well, such
as libchan.

Running parseVolumesFromSpec on all VolumesFrom specs before initialize
any mounts endures that we don't leave container.Volumes in an
inconsistent (partially initialized) if one of out mount groups is not
available (e.g. the container we're trying to mount from does not
exist).
Keeping container.Volumes in a consistent state ensures that next time
we Start() the container, it'll run prepareVolumes() again.
The attached test demonstrates that when a container fails to start due
to a missing container specified in VolumesFrom, it "remembers" a Volume
that worked.
Fixes: #8726
