    Fix Swift for multinode P+ACO deployment

    Current Swift playbook is based on the preassumption of AIO setup.
    However, if one goes with default multinode setup
    (ansible/inventory/multinode), it follows the P + ACO deployment model,
    which proxy-server runs on controller nodes where ACO
    (account/container/object services) run on storage nodes.

    It will break because swift proxy-server no longer has access (it
    shouldn't have) to /srv/node path. This change ensure disk mounting part
    only happens on storage node. It also moves chown from proxy-server
    Dockerfile to rsyncd because no matter with PACO, P+ACO or P+A+C+O
    model, rsyncd is always running on each storage node.
