    The file must contain non-empty lines, and each line must

    <user> <resource name> <capacity> <quantity> <import_limit> <export_limit>

    For example to grant the following user with 10 private networks
    (independent of any he receives from projects):

    6119a50b-cbc7-42c0-bafc-4b6570e3f6ac cyclades.network.private 10 0 1000000 1000000

    The last two values are arbitrarily large to represent no
    import/export limit at all.
