This commit cuts out the structure for defining grpc services for this
project. To provide compatibility with go package generation and support
reuse, we use a single protobuf file per package and make the import
paths relative to the GOPATH.
This first pass attempts to position the Mount type as the lingua franca
of ContainerKit. The Images service will provide paths prepared for use
as a set of mounts of the container service.
We'll need to merge the container service in place with new file defined
here.

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

Windows will not use containerd and its just unused code and unneed
complexity to keep it all around.
Signed-off-by: Michael Crosby <crosbymichael@gmail.com>
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()

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

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.

Convert pids in containerd to string
This is so that we no longer care about linux or system level pids and
processes in containerd have user defined process id(pid) kinda like the
exec process ids that docker has today.

This currently logs to a json file with the stream type. This is slow
and hard on the cpu and memory so we need to swich this over to
something like protobufs for the binary logs but this is just a start.
