Revert "Lets ensure the rootfs is always set before starting the container"

This reverts commit c6af4fab084cb1b920af513ef629d75745a152fc as it is
probably a better idea to have the rootfs config baked into the config
file so we can easily run a `lxc-start -n CONTAINER`
Ensure container's rootfs is set on config file

Makes our lives easier as we are able to just run a `lxc-start -n CONTAINER`
to check how things are doing without having to go through vagrant.
