Issue MESOS-5806: CNI isolator should prepare network related /etc/* files for containers using host mode but specify container images.
Currently, the CNI isolator will just ignore those containers that want to join the host network (i.e., not specifying NetworkInfo). However, if the container specifies a container image, we need to make sure that it has access to host /etc/* files. We should perform the bind mount for the container. This is also what docker does when a container is running in host mode.
