    Adds support to seperate Swift access and replication traffic from other
    storage traffic.

    In a deployment where both Ceph and Swift have been deployed,
    this changes adds functionalality to support optional seperation
    of storage network traffic. This adds two new network interfaces
    'swift_storage_interface' and 'swift_replication_interface' which maintain
    backwards compatibility.

    The Swift access network interface is configured via 'swift_storage_interface',
    which defaults to 'storage_interface'. The Swift replication network
    interface is configured via 'swift_replication_interface', which
    defaults to 'swift_storage_interface'.

    If a separate replication network is used, Kolla Ansible now deploys separate
    replication servers for the accounts, containers and objects, that listen on
    this network. In this case, these services handle only replication traffic, and
    the original account-, container- and object- servers only handle storage
    user requests.
