This fix tries to address the issue raised in 24881 where
the stack name is not visable when inspecting containers
deployed through stacks.
This fix adds `labelNamespace` (`com.docker.stack.namespace`)
to containers at the client side so that the stack name label
will show up after containers are deployed.
This fix is tested manually:
- Build the binary with `make DOCKER_EXPERIMENTAL=1`
- Create a bundle file and deploy with the `docker stack deploy`
- Verify that `com.docker.stack.namespace` has been
set properly by checking contaners with `docker inspect <ContainerID>`
This fix fixes 24881.
