Title: Add ExecIDs to docker inspect

I need this for docker swarm because right now there is no way from the API to tell an execID is lined to a container.

Swarm has a mapping container <---> node so when Swarm receives a `/container//kill` request, we can use the `` to find the right host to proxy the request to.

When Swarm receives a `/exec//start` there is no way to find the right host right now.
