See https://github.com/docker/docker/issues/22643 for an example
where we get an error running a cmd but there's no output so `b`
is an empty string, which means the user doesn't see any interesting
error message to help them.
This PR will send back the `err` and `b` so that between those two
bits of info they should get something more than a blank string.

Because we are launching alot of different runc commands to do
operations there is a race between doing a `cmd.Wait()` and getting the
sigchld and reaping it. We can remove the sigchild reaper from
containerd as long as we make sure we reap the shim process if we are
the parent, i.e. not restored.

runc `events --stats` now has stable output so we don't need to bind to
libcontainer directly to get stats output for the containers.

runc now has a `ps` command with json output to support listing all the
processes inside a container. We no longer need to use libcontainer
directly for doing this.

Windows will not use containerd and its just unused code and unneed
complexity to keep it all around.

This currently depends on a runc PR:
https://github.com/opencontainers/runc/pull/703
We need this pr because we have to SIGKILL runc and the container root
dir will still be left around.
As for the containerd changes this adds a flag to containerd so that you
can configure the timeout without any more code changes. It also adds
better handling in the error cases and will kill the containerd-shim and
runc ( as well as the user process if it exists ) if the timeout is hit.

This allows you to pass options like:
```bash
containerd --debug --runtime-args "--debug" --runtime-args
"--systemd-cgroup"
```

If the shim gets sigkilled while containerd is down we need to be able
to remove the container correctly so that it does not stay in a stopped
state forever.

Move process sorter to new file

Sort containers by id
This will not be the most accurate sorting but atleast the list will be
consistent inbetween calls.

Allow runtime to be configurable via daemon start
This allows people to pass an alternate name or location to the runtime
binary to start containers.

Fix state output for containers
Return the proper state/status for a container by checking if the pid is
still alive. Also fix the cleanup handling in the shim to make sure
containers are not left behind.
