Windows is not going to use containerd because there is already a
similar implementation on windows. This removes all the windows files
because there is no reason to keep this overhead when its not going to
be used.

Prior to this patch, when list containers by "ctr containers" or
"ctr containers xxx", it will not get the proper status of conatinser(s).
That was caused by the wrong implementation of State() for structure process,
it only send a signal "0" to ping the "init" process and do nothing.
Since the OCI/runc has implemented an interface Status(), we can use that.
And I think this is more compatible with the design for containerd:
- containerd -> runtime -> fun()

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 containerd binary is renamed to docker-containerd, then it should
invoke the docker-containerd-shim binary.

If we fail to exec a process make sure that it is cleaned up within the
container's information and on disk state.

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.

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.
