LXC containers missing rootfs dir

[Matt Thompson]

I've noticed something odd and believe it's a result of https://review.openstack.org/#/c/190048/8. Currently, a container's rootfs is in /var/lib/lxc/<container>. For example:

root@jenk-heat-350-node1:/var/lib/lxc# ls -al jenk-heat-350-node1_cinder_api_container-32e9101e
total 104

Previously, the rootfs would have been in /var/lib/lxc/<container>/rootfs.

This new behaviour is quite messy as it's going to become difficult to determine what files are LXC configuration versus files within the rootfs.

    Create LXC containers with a rootfs dir

    Previously, an LXC container's rootfs was being placed into
    /var/lib/lxc/<container>/rootfs. Commit
    https://review.openstack.org/#/c/190048/8 inadvertently changed this so
    that a container's rootfs is now placed into /var/lib/lxc/<container/.
    The downside here is that we now have a directory containing a
    container's root fs and the LXC configuration for the container.

    This change creates a new role-level variable called
    lxc_container_rootfs_directory which defaults to
    "{{ lxc_container_directory }}/{{ container_name }}/rootfs" and passes
    this variable when creating the container.
